<h2> <span class="mw-headline">How to access</span></h2>
<p>
Select <b>Help --&gt; System Info</b> from the drop-down menu on the Back-end of your Joomla! installation.
</p>
<a title="Description" name="Description"></a>
<h2> <span class="mw-headline">Description</span></h2>
<p>
The System Info screens provides useful information about your host
server environment, including operating system, PHP settings, and
directory access settings. You can navigate to five different screens:
System Info, PHP Settings, Configuration File, Directory Permissions,
and PHP Information. Each screen provides detailed information about
that aspect of your Joomla! web site.
</p>
<p>
This information is very helpful when you are troubleshooting
setup problems. Note that none of these settings can be changed from
these screens. That must be done in other places, depending on the
specific setting. The settings in the Configuration File screen can be
changed from the <a href="index.php?option=com_content&amp;task=view&amp;id=1445&amp;Itemid=278" target="_self" title="Screen.config.15">Global Configuration</a> screen. The other settings shown here depend on your host server configuration and cannot be changed from inside Joomla!

<a title="Configuration_File" name="Configuration_File"></a>
<h2> <span class="mw-headline">Configuration File</span></h2>
<p>
This screen shows the contents of the current Joomla! <i>configuration.php</i> file which is stored under the main <b>joomla_root/</b>
directory. This file is created for you automatically when you first
install Joomla! and where most changes of the Global Configuration
section of Joomla! are recorded. Please note that none of the settings
can be changed from this page. Use the <a href="index.php?option=com_content&amp;task=view&amp;id=1445&amp;Itemid=278" target="_self" title="Screen.config.15">Global Configuration</a> to see more information about these settings and to make changes.
</p>
<a title="Directory_Permissions" name="Directory_Permissions"></a>
<h2> <span class="mw-headline">Directory Permissions</span></h2>
<p>
This screen shows a list of the directories that the webserver
should have write access to. Please note that all directories listed on
this page should say <b style="color: green">Writable</b>. If not, you may need to change the permissions to be able to install and use Joomla! successfully.
</p>
<a title="PHP_Information" name="PHP_Information"></a>
<h2> <span class="mw-headline">PHP Information</span></h2>
<p>
This screen displays the full configuration of the PHP server side
scripting language that Joomla! runs on, together with all the
associated system information that goes towards the creation of the web
server. It is the output of an integrated php.info script built into
Joomla!.
</p>
<p>
PHP is installed, and runs on the server (hence the server
side above), and therefore all the settings are made on the server. The
visitor to the web site does not need to have anything special running
on their local machine in order to view or use any of the extra
functionality that PHP gives to the web site.
</p>
<p>
All the settings that are ever likely to be needed are displayed here. Any changes that are required would be made within the <i>php.ini</i> and other configuration files on the web server.
</p>
<p>
How much control a web site owner has over this information
depends on whether they own the server or if the server host is
flexible in their customer approach.
</p>
<p>
It is a good practice to know the limitations of a particular
server installation. This screens output is used to find detailed
information about how PHP is implemented on the server.

If you are having problems installing extensions, uploading, or
changing configuration options, check the Directory Permissions screen
to make sure you have permission to write to files on your web server.
The &quot;Status&quot; of the directories should be &quot;Writable&quot;. If not, you may
be unable to upload or edit files in these directories.

When you are seeking help with setup problems, for example in
