Site System Information/tr
From Joomla! Documentation
Joomla! Core settings with information useful for management of your Joomla! website.
This tool provides useful information about your host server environment, including operating system, database and PHP settings, and directory information. You can navigate to five different screen: System Info, PHP Settings, Configuration File, Folder Permissions, and PHP Information. Each screen provides detailed information about that aspect of your Joomla! website. This information is very helpful when you are troubleshooting setup problems.
- Note that none of these settings can be changed from these screens. This must be done in different locations throughout your Joomla! installation, depending on the specific setting.
- Many settings on the Configuration File screen can be changed from the Global Configuration screen. Some settings shown here depend on your host server configuration and cannot be changed from inside Joomla!.

This screen shows the contents of the current Joomla! configuration.php file which is stored under the main <path to joomla>/joomla_root/ 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 Global Configuration to see more information about these settings and to make changes.
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 Writable. If not, you may need to change the permissions to be able to install and use Joomla! successfully.
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!.
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.
All the settings that are ever likely to be needed are displayed here. Any changes that are required would be made within the php.ini and other configuration files on the web server.
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.
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.
For full details on the information contained within the PHP Info screen visit: http://php.net/phpinfo.
At the top left you will see the toolbar:

- If you are having problems installing extensions, uploading files, or changing configuration options, check the Directory Permissions screen to make sure you have permission to write to files on your web server.
