What is it

PH Cloud is:

  1. DAV server
  2. DAV web client
  3. IMAP/SMTP email web client

If you do not know what is DAV check this FAQ.

You have the option to use all, or one of the above functionalities, depended on yours, or company's needs.

One server, many clients

With PH Cloud each of Joomla! users can have access to one DAV server link, and may login with their Joomla! user password, but they have access to create many DAV and Email clients. That means one user can have access to all his emails, files, calendars, contacts from various providers, on a single web page.

How it works

When a user login to Joomla!, and access PH Cloud, has the ability to create unlimited Accounts. Each account correspond to a different email, or DAV server.



After you install it for the first time, make sure you activate the related plugin, if it is not already activated. 

Updating to the latest release

The extension can be updated with two different methods:

  1. By installing the new version on top of the old one.
  2. By using the integrated Remote Update system of Joomla! extensions manager.

Updating directly

This is the failsafe approach, but the least convenient.

  1. Download the latest release from our site and save the ZIP file to your hard disk.
  2. Then log in to your site's back end and click on Joomla! Extensions Manager.
  3. Use the Browse... button to locate the ZIP file you downloaded, then click on Upload and Install.

All Joomla! versions since 1.5.5 are smart enough to understand that you're doing an upgrade instead of installation, so they adjust the process accordingly.

Do NOT uninstall the current version of the extension before updating it. Uninstalling it will remove all of your data.

Using Remote Update

Firstly, insert from Extension's Options your download ID. You can get your download id at Your Download ID.

Then go to Joomla! extensions manager -> update tab and click button Find Updates. If a new release is appeared then you can just update it from there.

Something not working right after the update?

Sometimes Joomla! "forgets" to copy all updated files. Fortunately, this is something that we have seen a few times. In this case, simply follow the instructions in the Updating Directly section above. This will force Joomla! to retry updating the component, copying the missing files and everything will work again.


You can uninstall the component just like any other Joomla! component.

  1. In your site's back-end, just go to Extensions Manager and click on Uninstall.
  2. In the Filter area type PH Cloud and click on Search.
  3. Several entries appear. Select the entry where the Type is Package. Do not select the other entries; they are removed automatically.
  4. Now click on Uninstall. This will completely remove extension including all related data.



With the installation a default category is created. This category is used by the accounts. You may create new, edit etc. as the Joomla! standard categories.


Next you have to go at least once in the component's options (settings) and save.


First thing to configure is to create a new contact's category from your back end->SP Mail Client->Categories. That should be the category where contact's (address book) for each user will be saved. Note that each user can view only his contacts and not any other.

Auto save contacts? - Choose this option to yes if you want to automatically save contacts to Address Book every time you send an email.

Accounts Category - The default accounts category. When a new user uses PH Cloud automatically a default account is created. Choose here the category to save the accounts.

Accounts Access - The Joomla! access level the default accounts will have.

Under iFrame - Choose this option if you wish to integrate with other extensions. For more information see article "Integrate with other extensions"

Show Time? - Choose this option if you wish to see the date and time on front end.

Class Styling - The rest options is for how the emails appears in front end. That is useful if you wish to use your templates styling for tables.


It is very important thing to define security as per your needs. The access to the component is defined by the standard Joomla! Access Control List (ACL), for maximum security and compatibility. For example, if you plan for your registered users to use the component in front end we recommend below settings.

Keep in mind that by default the registered group does not have all the necessary access.


List View

From the Accounts View the user may create, edit, delete etc. his web client accounts. An account may point to the same local server, or to any other remote server. Below in edit view, things but come more clear.

Edit View

When you edit/add an account there various tabs where user must define the necessary remote server credentials.

General Tab

In this tab actually you define the name you wish and access level of the account. Also you may choose the default account. You may only have one default account, and you can't delete it. This is the account the user will see by default when at first access the system.

Emails Configuration Tab

Here user may setup everything to use an IMAP\SMTP email client. All necessary information should be available by the user's email host provider. It is not necessary to setup the email client if you do not wish to use it, but PH Cloud might be the best web solution to have access to all the emails from one web place.

DAV Client Configuration Tab

If you leave empty the DAV configuration fields, then by default the local host is used. Still you might wish to connect to other remote DAV servers. This is where you put the necessary credentials.

Publishing Tab

From this tab you may define change the category, or the user if you have the necessary access. The user is the one who have access to this account.


Integrate with other extensions

Actually the component takes advantage the magic Joomla! variable tmpl=component where you can strip the template and just show the component itself. With this ability, you can use for an example an iframe, to show the component as a part of any other extension you might have. You can even add it within an article, given that your editor does not strip the html tags.

The first thing to do is to go to SP Mail Client options, and set option to work with irame as Yes.

Then you must create front end menu. To do that from the back end, menu manager, you just add a new menu item, and select SP Mail Client, as below image.

After that and we assume that you use sef, then just add the iframe any place you wish. The url to add in iframe should be: ''. The result should be something like below image!

If for some reason you added the iframe as a unique url, if you press the envelope url in the navigation bar, then you will be redirected to the home page of your site.

Synchronizing Calendars Using CalDAV

Calendaring Extensions to WebDAV, referred to as CalDAV, enables clients to access scheduling information on remote servers. As an extension to WebDAV, CalDAV (defined by RFC 4791) uses the iCalendar format to manage calendar data. CalDAV enables multiple clients to access the same information for use in cooperative planning and information sharing.

The Calendar app provides both the Primary CalDAV address and the iOS/OSX CalDAV address. Using these addresses, you can use CalDAV-compatible programs (for example, Kontact, Evolution, or Mozilla Thunderbird with the Lightning Add-on) using the address provided.


The Lightning Add-on doesn’t support using multiple accounts on a single server as a default. You need to set to true in the Config Editor of Mozilla Thunderbird to be able to use multiple accounts.

In DAV Server view you can get the Primary CalDAV address. The link is:

Synchronizing with OS X

The setup is basically the same as with iOS using the path ADDRESS/phcloud/caldav.php/principals/username/ to sync with PH Cloud. For OS X 10.7 Lion and 10.8 Mountain Lion everything works fine, but OS X 10.6 (Snow Leopard) and older needs some fiddling to work. A user contributed the following:

  1. Make sure, addressbook is not running. If it is, select the windows and press Command + Q to terminate it.
  2. Navigate to /Users/YOUR_USERNAME/Library/Application Support/AddressBook/Sources. If you have all ready some kind of addressbook setup, it is likely you will see some folders named like this BEA92826-FBF3-4E53-B5C6-ED7C2B454430. Note down what folders there are now and leave the window open.
  3. Open addressbook and try to add a new CardDav addressbook. At this point, it does not matter what information you enter. It will come up with the same error message you mentioned before when you click “Create”. Ignore it and click “Create” again. A non-functional addressbook will be added.
  4. Close addressbook again using Command + Q
  5. Go back to the folder window from step 2. You will now see a newly created folder with another long string as its name.
  6. Navigate to the newly created folder and edit the Configuration.plist with your favorite text editor.
  7. Search for a section looking like this:
<key>servername</key> <string>http://:0(null)</string> <key>username</key> <string>Whatever_you_entered_before</string>
  1. Make it look like this. Please note that the :80 after YOUR_DOMAIN is important:
<key>servername</key <string>http://YOUR_DOMAIN:80/phcloud/carddav.php/principals/username</string> <key>username</key <string>username</string>
  1. Save the file and open addressbook again. It will not work yet.
  2. Open the preferences for your PH Cloud CardDAV-Account and enter your password.
  3. You may have to restart addressbook once more. After this, it should work.

Thunderbird - Synchronize Addressbook


  1. Thunderbird for your OS unless it comes with your OS distribution (Linux)
  2. Sogo Connector (latest release)
  3. Lightning (a Thunderbird calendar add-on. At the time (Aug 14), syncing your contacts only works with this add-on installed.)

With an installed Thunderbird mailtool, an installed SoGo Connector, and an installed Lightning add-on:

  1. Thunderbird Addressbook is in the Thunderbird “Tools” Menu
  2. In the Thunderbird Addressbook application:
  3. “File > New > Remote Addressbook” (SoGo Connector added this)
  4. Name:” is the name you want to give your Addressbook in the Thunderbird addressbook bar area
  5. URL:” is

in the -bottom left- of the Contacts View (same symbol as found in the -top right- in the Calendar view). Then look for a little impeller symbol

which will display the URL you need for your installation to work.

Once installed, synchronize (right click on your newly made remote address book and select “Synchronize”). You’ll see your address book populate from PH Cloud! Don’t click “read only” above unless you don’t want to modify your PH Cloudserver addressbook, like it contains a listing of corporate contacts and is shared with lots of people, and you don’t want a new user dragging it somewhere unintended.

The rest of the details of dealing with Thunderbird addressbook are left to the reader... First thing I learned is dragging a contact to a different addressbook is a “move” operation. If you are worried about losing the contact, save it to a VCF file using PH Cloud(Or LDIF using Thunderbird Addressbook) first! Like dragging from “PH Cloud Addressbook” to “Personal Address Book” removes the contact from PH Cloud Server (deleting it from all the other synchronized installations) and puts it in your Local Machine -only- Address Book. So be careful or you’ll have unintended consequences where you might have intended a “copy” operation.

Contact Pictures are also sync’ed!


BlackBerry OS 10.2

BlackBerry OS up to 10.2.2102 does not accept a URL with protocol https:// in front of the server address. It will always tell you that it cannot login on your server. So instead of writing:


in the server address field, you have to write:



Accessing your Files Using the PH Cloud Web Interface

PH Cloud Files web interface allow the follow operations:


Click the file name to view file in browser.


Click the download icon to download the file to your computer.


Displays older versions, if there are any, and you can revert to an older file version.


Delete the selected file or folder.

Previewing Files

You can display the various files in the browser by clicking on the file name. It depends on your browser capability of what you see and not what. If your browser cannot display a file, it starts a download process and downloads the file to your computer.

Video streaming also depends on your Web browser and the video format.

Navigating Inside Your files

Navigating through folders in PH Cloud is as simple as clicking on a folder to open it and using the back button on your browser to move to a previous level. PH Cloud also provides a navigation bar at the top of the Files field for quick navigation.

The navigation bar functions as a “breadcrumb” locator. It displays your current directory and enables you to migrate back to one of the upper directories or, using the home icon, to navigate back into your root folder.

Creating or Uploading Files and Directories

PH Cloud enables you to upload new files and create new folders directly in a folder by clicking on the corresponding buttons.

Selecting Files and folders

You can select one or more files or folders by clicking on the small check box that represent them. When you select a file or folder, a small checkbox is populated with a check to indicate that it is selected. To select all files in the current directory, you can click on the checkbox located at the top of the Files app field, above the first file or folder on the list.

If you select multiple files, you can delete all of the selected files by using the Delete button.

Desktop and Mobile Clients

In all devices there are various clients applications you can use to connect to PH Cloud from your mobile device using WebDAV. The URL to use on these is:

Username and password are the same as your Joomla! login.

WebDAV Configuration

If you prefer, you may also connect your desktop PC to your PH Cloud server by using the WebDAV protocol rather than using a special client application. Web Distributed Authoring and Versioning (WebDAV) is a Hypertext Transfer Protocol (HTTP) extension that makes it easy to create, read, and edit files on Web servers. With WebDAV you can access your PH Cloud files on Linux, Mac OS X and Windows in the same way as any remote network share, and stay synchronized.


In the following examples, You must adjust to the URL of your Joomla site link.

Accessing Files Using Linux

You can access files in Linux operating systems using the following methods.

Nautilus File Manager

Use the davs:// protocol to connect the Nautilus file manager to your PH Cloud share:



If your server connection is not HTTPS-secured, use dav:// instead of davs://.

Accessing Files with KDE and Dolphin File Manager

To access your PH Cloud files using the Dolphin file manager in KDE, use the webdav:// protocol:


You can create a permanent link to your PH Cloud server:

  1. Open Dolphin and click “Network” in the left hand “Places” column.
  2. Click on the icon labeled Add a Network Folder. The resulting dialog should appear with WebDAV already selected.
  3. If WebDAV is not selected, select it.
  4. Click Next.
  5. Enter the following settings:
  6. Name: The name you want to see in the Places bookmark, for example PH Cloud.
  7. User: The PH Cloud username you used to log in, for example admin.
  8. Server: The PH Cloud domain name, for example (without http:// before or directories afterwards).
  9. Folder – Enter the path phcloud/webdav.php/WebDAV.
  10. (Optional) Check the “Create icon checkbox” for a bookmark to appear in the Places column.
  11. (Optional) Provide any special settings or an SSL certificate in the “Port & Encrypted” checkbox.

Creating WebDAV Mounts on the Linux Command Line

You can create WebDAV mounts from the Linux command line. This is useful if you prefer to access PH Cloud the same way as any other remote filesystem mount. The following example shows how to create a personal mount and have it mounted automatically every time you log in to your Linux computer.

  1. Install the davfs2 WebDAV filesystem driver, which allows you to mount WebDAV shares just like any other remote filesystem. Use this command to install it on Debian/Ubuntu:
apt-get install davfs2
  1. Use this command to install it on CentOS, Fedora, and openSUSE:
yum install davfs2
  1. Add yourself to the davfs2 group:
usermod -aG davfs2 <username>
  1. Then create a phcloud directory in your home directory for the mountpoint, and .davfs2/ for your personal configuration file:
mkdir ~/phcloud
mkdir ~/.davfs2
  1. Copy /etc/davfs2/secrets to ~/.davfs2:
cp  /etc/davfs2/secrets ~/.davfs2/secrets
  1. Set yourself as the owner and make the permissions read-write owner only:
chown <username>:<username>  ~/.davfs2/secrets
chmod 600 ~/.davfs2/secrets
  1. Add your PH Cloud login credentials to the end of the secrets file, using your PH Cloud server URL and your PH Cloud username and password:<username> <password>
  1. Add the mount information to /etc/fstab:<username>/phcloud
davfs user,rw,auto 0 0
  1. Then test that it mounts and authenticates by running the following command. If you set it up correctly you won’t need root permissions:
mount ~/phcloud
  1. You should also be able to unmount it:
umount ~/phcloud

Now every time you login to your Linux system your PH Cloud share should automatically mount via WebDAV in your ~/phcloud directory. If you prefer to mount it manually, change auto to noauto in /etc/fstab.

Known Issues


Resource temporarily unavailable


If you experience trouble when you create a file in the directory, edit /etc/davfs2/davfs2.conf and add:

use_locks 0

Certificate warnings


If you use a self-signed certificate, you will get a warning. To change this, you need to configure davfs2 to recognize your certificate. Copy mycertificate.pem to /etc/davfs2/certs/. Then edit /etc/davfs2/davfs2.conf and uncomment the line servercert. Now add the path of your certificate as in this example:

servercert   /etc/davfs2/certs/mycertificate.pem

Accessing Files Using Mac OS X


The Mac OS X Finder suffers from a series of implementation problems and should only be used if the PH Cloud server runs on Apache and mod_php.

To access files through the Mac OS X Finder:

  1. Choose Go > Connect to Server.
The “Connect to Server” window opens.
  1. Specify the address of the server in the Server Address field.
For example, the URL used to connect to the PH Cloud server from the Mac OS X Finder is:
  1. Click Connect.
The device connects to the server.

Accessing Files Using Microsoft Windows

To use the native Windows implementation, you can map PH Cloud to a new drive. Mapping to a drive enables you to browse files stored on an PH Cloud server the way you would files stored in a mapped network drive.


Prior to mapping your drive, you must permit the use of Basic Authentication in the Windows Registry. The procedure is documented in KB841215 and differs between Windows XP/Server 2003 and Windows Vista/7. Please follow the Knowledge Base article before proceeding, and follow the Vista instructions if you run Windows 7.

Mapping Drives With the Command Line

The following example shows how to map a drive using the command line. To map the drive:

  1. Open a command prompt in Windows.
  2. Enter the following line in the command prompt to map to the computer Z drive:
net use Z: https://<drive_path>/phcloud/webdav.php /user:youruser
where <drive_path> is the URL to your PH Cloud server.

For example: net use Z: /user:youruser yourpassword

The computer maps the files of your PH Cloud account to the drive letter Z.


Though not recommended, you can also mount the PH Cloud server using HTTP, leaving the connection unencrypted. If you plan to use HTTP connections on devices while in a public place, we strongly recommend using a VPN tunnel to provide the necessary security.

An alternative command syntax is:

net use Z: \\\phcloud\webdav.php /user:youruser

Mapping Drives With Windows Explorer

To map a drive using the Microsoft Windows Explorer:

  1. Migrate to your computer in Windows Explorer.
  2. Right-click on Computer entry and select Map network drive... from the drop-down menu.
  3. Choose a local network drive to which you want to map PH Cloud.
  4. Specify the address to your PH Cloud instance, followed by /webdav.php
For example:


For SSL protected servers, check Reconnect at logon to ensure that the mapping is persistent upon subsequent reboots. If you want to connect to the PH Cloud server as a different user, check Connect using different credentials.

  1. Click the Finish button.
Windows Explorer maps the network drive, making your PH Cloud instance available.

Accessing Files Using Cyberduck

Cyberduck is an open source FTP and SFTP, WebDAV, OpenStack Swift, and Amazon S3 browser designed for file transfers on Mac OS X and Windows.


This example uses Cyberduck version 4.2.1.

To use Cyberduck:

  1. Specify a server without any leading protocol information. For example:

2. Specify the appropriate port. The port you choose depends on whether or not your PH Cloud server supports SSL. Cyberduck requires that you select a different connection type if you plan to use SSL. For example:

80 (for WebDAV)
443 (for WebDAV (HTTPS/SSL))

3. Use the ‘More Options’ drop-down menu to add the rest of your WebDAV URL into the ‘Path’ field. For example:


Now Cyberduck enables file access to the PH Cloud server.

Known Problems


Windows does not connect using HTTPS.

Solution 1

The Windows WebDAV Client might not support Server Name Indication (SNI) on encrypted connections. If you encounter an error mounting an SSL-encrypted PH Cloud instance, contact your provider about assigning a dedicated IP address for your SSL-based server.

Solution 2

The Windows WebDAV Client might not support TSLv1.1 / TSLv1.2 connections. If you have restricted your server config to only provide TLSv1.1 and above the connection to your server might fail. Please refer to the WinHTTP documentation for further information.


You receive the following error message: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved.


Windows limits the maximum size a file transferred from or to a WebDAV share may have. You can increase the value FileSizeLimitInBytes in HKEY_LOCAL_MacHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters ** by clicking on **Modify.

To increase the limit to the maximum value of 4GB, select Decimal, enter a value of 4294967295, and reboot Windows or restart the WebClient service.


Accessing your files from Microsoft Office via WebDAV fails.


Known problems and their solutions are documented in the KB2123563 article.


Cannot map PH Cloud as a WebDAV drive in Windows using self-signed certificate.

  1. Go to the your PH Cloud instance via your favorite Web browser.
  2. Click through until you get to the certificate error in the browser status line.
  3. View the cert, then from the Details tab, select Copy to File.
  4. Save to the desktop with an arbitrary name, for example phcloud.cer.
  5. Start, Run, MMC.
  6. File, Add/Remove Snap-In.
  7. Select Certificates, Click Add, My User Account, then Finish, then OK.
  8. Dig down to Trust Root Certification Authorities, Certificates.
  9. Right-Click Certificate, Select All Tasks, Import.
  10. Select the Save Cert from the Desktop.
  11. Select Place all Certificates in the following Store, Click Browse,
  12. Check the Box that says Show Physical Stores, Expand out Trusted Root Certification Authorities, and select Local Computer there, click OK, Complete the Import.
  13. Check the list to make sure it shows up. You will probably need to Refresh before you see it. Exit MMC.
  14. Open Browser, select Tools, Delete Browsing History.
  15. Select all but In Private Filtering Data, complete.
  16. Go to Internet Options, Content Tab, Clear SSL State.
  17. Close browser, then re-open and test.

You cannot download more than 50 MB or upload large Files when the upload takes longer than 30 minutes using Web Client in Windows 7.


Workarounds are documented in the KB2668751 article.
