The Global Configuration screen allows you to configure the Joomla site with your personal settings. Settings made in this screen apply to the whole site.
How to access
- System → Setup Panel → Global Configuration
- Site Name. Enter the name of the website. This will be used in various locations (for example the Backend browser title bar and Site Offline pages).
- Site Offline. Select whether access to the Frontend is available.
- Offline Message.
- Use Custom Message: The message uses the value defined in the 'Custom Message' field.
- Use Site Language Default Message: The message uses the value defined in the site language ini file.
- Offline Image. Select an image to be displayed on the offline page. Make sure the image is less than 400px wide.
- Offline Message.
- Frontend Editing. Select editing for modules and menu items.
- Default Editor. Select the default text editor. Registered Users will be able to change their preference in their personal details.
- Default Captcha. Select the default captcha for your site. You may need to enter required information in the captcha plugin.
- Default Access Level. Select the default access level for new items.
- Default List Limit. Sets the default length of lists in the Backend for all users.
- Default Feed Limit. Select the number of content items to show in the feeds.
- Feed Email Address. The RSS and Atom newsfeeds include the author's email address.
- Site Meta Description. Enter a description of the overall website that is to be used by search engines.
- Robots. Robots instructions.
- index, follow: Index this page and follow the links on this page.
- noindex, follow: Do not index this page, but still follow the links on the page. For example, you might do this for a site map page where you want the links to be indexed but you don't want this page to show in search engines.
- index, nofollow: Index this page, but do not follow any links on the page. For example, you might want to do this for an events calendar, where you want the page to show in search engines but you do not want to index each event.
- noindex, nofollow: Do not index this page or follow any links on the page.
- Content Rights. Describe what rights others have to use this content. This is conveyed to search engines using the 'rights' meta tag in the HTML head.
- Author Meta Tag. Show the author meta tag when viewing articles.
- Joomla Version. Controls whether the 'generator' meta tag in the HTML document's header in the Frontend and in Atom feeds includes the exact version of the Joomla site. It is recommended to hide it for security reasons.
- Search Engine Friendly URLs. Select if the URLs are optimised for Search Engines.
- Use URL Rewriting.
- Apache and Litespeed: Rename 'htaccess.txt' to '.htaccess'
- IIS: Rename 'web.config.txt' to 'web.config'
- NginX: you must configure your server
- Other servers or if unsure: please consult your hosting company
- Add Suffix to URL. If yes, the system will add a suffix to the URL based on the document type.
- Unicode Aliases. Choose between transliteration and unicode aliases. Transliteration is the default.
- Site Name in Page Titles. Begin or end all Page Titles with the site name (for example, "My Site Name - My Article Name").
- Cookie Domain. Domain to use when setting session cookies. Precede domain with '.' if cookie should be valid for all subdomains.
- Cookie Path. Path the cookie should be valid for.
- Debug System. If enabled, diagnostic information, language translation, and SQL errors (if present) will be displayed. The information will be displayed at the foot of every page you view within the Joomla Backend and Frontend. It is not advisable to leave the debug mode activated when running a live website.
- Debug Language. Select if the debugging indicators (**...**) or (??...??) for the Joomla! Language files will be displayed. Debug Language will work without Debug System being activated, but you will not get the additional detailed references that will help you correct any errors.
- System Cache. Enable or disable caching and set caching level. Conservative level: smaller system cache, Progressive level (default): faster, bigger system cache, includes module renderers cache. Not appropriate for extremely large sites.
- Cache Handler. (File). Choose the cache handler. Native caching mechanism is file-based. Please make sure the cache folders are writable.
- Platform Specific Caching. Enable or disable platform specific caching. Enable when HTML output on mobile differs from other devices. (Default disabled.)
- Cache Time (minutes). The maximum length of time in minutes for a cache file to be stored before it is refreshed.
- Path to Cache Folder. Specify a writable folder to store cache files if you do not wish to use the default folder.
- Session Handler. The mechanism by which Joomla identifies a User once they are connected to the website using non-persistent cookies.
- The database session handler is the default handler because it is the only one that Joomla can fully configure and control on its own.
- The filesystem handler will be slightly more performant than the database handler, but it requires PHP to be configured properly otherwise it will crash and Joomla will be totally unusable. To use it, select Filesystem and then enter a full filesystem path in the Session Save Path field that appears. Ensure the path has appropriate permissions for PHP to read and write files, and if session garbage collection is enabled to delete files from it. If this path is not set, Joomla will rely on the PHP session.save_path INI configuration or fallback to the system temporary directory (as defined by the sys_get_temp_dir() PHP function). If neither of those paths are configured or the permissions are wrong then it's game over. To recover, edit the configuration.php file and set $session_handler = 'database'.
- Other handlers (APCu, Memcached, Redis, and WinCache) all rely on optional PHP extensions and may be available if your system supports them. APCu or WinCache may be no better than the "plain" filesystem option. The Memcached and Redis handlers are overkill for Joomla in a typical shared hosting environment. Those types of handlers succeed if you are deploying Joomla in a load balanced environment where multiple servers are involved and you need the session data for the application to be available across all servers.
- Session Lifetime (minutes). Auto log out a User after they have been inactive for the entered number of minutes. Do not set too high.
- Shared Sessions. When enabled, a user's session is shared between the Frontend and Backend sections of the site. Note that changing this value will invalidate all existing sessions on the site.This is not available when the 'Force HTTPS' option is set to 'Administrator Only'.
- Track Session Metadata.
- Yes: Additional metadata about a user's session (including their username, user ID, and which application they are logged into) will be logged to the session database table.
- No: Features dependent on this data will be unavailable.
- Path to Temp Folder. Please specify a writable folder to store temporary files.
- Gzip Page Compression. Compress buffered output if supported.
- Error Reporting. This parameter sets the level of error reporting to be used by PHP on the Joomla site. It has five options: System Default, None, Simple, Maximum and Development. “System Default” leaves the level of PHP error reporting to that set up in the server (usually in the php.ini file). “None” switches off PHP error reporting, and “Simple”, “Maximum” and “Development” override the server setting to give a basic level of reporting (for “Simple”) and the reporting of all errors (“Maximum” and “Development”).
Tip. Should your Joomla site fail to the extent that it is not possible to use the administrator page to activate error reporting, you can switch on full PHP error reporting by editing the configuration.php file. Changing the $error_reporting parameter in that file to a value of 'maximum' is the equivalent to setting Error Reporting to “Maximum”.
- Force HTTPS. Force site access in the selected areas to occur only with HTTPS (encrypted HTTP connections with the https:// protocol prefix) and also force the use of secure cookies. Note, you must have HTTPS enabled on your server to utilise this option.
- Website Time Zone. Choose a city in the list to configure the date and time for display.
- Enable CORS. Enable Cross-Origin Resource Sharing (CORS)
- Behind Load Balancer. If your site is behind a load balancer or reverse proxy, enable this setting so that IP addresses and other configurations within Joomla automatically take this into account.
- Enable Outbound Proxy. Some hosts do not allow any network access from your site to the outside world by default and require you to manually configure an outbound proxy.
- Outbound Proxy Host. Host (domain) name or IP address.
- Outbound Proxy Port.
- Outbound Proxy Username. Leave blank if your outbound proxy does not require authentication.
- Outbound Proxy Password.
- Database Type. The type of database in use, selected during the installation process. Do not edit this field unless you are migrating to a different type of database, perhaps due to changing your hosting provider.
- Host. The hostname for your database entered during the installation process. Do not edit this field unless absolutely necessary (eg the transfer of the database to a new hosting provider).
- Database Username. The username for access to your database entered during the installation process. Do not edit this field unless absolutely necessary (eg the transfer of the database to a new hosting provider).
- Database Password. The password to be used to access the database. Do not edit this field unless absolutely necessary (eg. after the transfer of the database to a new hosting provider).
- Database Name. The name for your database entered during the installation process. Do not edit this field unless absolutely necessary (eg the transfer of the database to a new hosting provider).
- Database Tables Prefix. The prefix used for your database tables, created during the installation process. Do not edit field unless absolutely necessary (eg the transfer of the database to a new hosting provider).

These text filter settings will be applied to all text editor fields submitted by users in the selected groups.
These filtering options give more control over the HTML your content providers submit. You can be as strict or as liberal as you require to suit your site's needs. The filtering is opt-in and the default settings provide good protection against markup commonly associated with website attacks.

- Save & Close. Saves the options and closes the current screen.
- Close. Closes the current screen and returns to the previous screen without saving any modifications you may have made.
- Toggle Inline Help. Show help text below some options.
- Help. Opens this help screen.
- Most, if not all, of these settings can be set once and then left alone.
- If major modifications need to be made, then consider taking the site offline to test it and to make sure everything is in working order.
- The settings are saved in '<Joomla-root>/configuration.php'. You have to either activate the FTP-layer or make the 'configuration.php' file writable to save your changes.
