Help4.x:Site Global Configuration
From Joomla! Documentation
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
- Select System → Setup Panel → Global Configuration in the Administrator menu.
Many of the form field values are stored in the configuration.php file in the root of your site.
Part of the Site Tab is illustrated in the Screenshot. There is a complete image of the Site Tab to look at if you need it.
- Site Name: Enter the name of your Web site. This will be used in various locations (e.g. the backend browser title bar and Site Offline pages).
- Site Offline: (Yes/No). Select whether access to the Site frontend is available. If Yes, the frontend will display or not a message depending on the settings below.
- Offline Message: (Hide/Use Custom Message/Use Site Language Default Message). Display or not a frontend message when the site is offline. The custom offline message uses the value defined in the 'Custom message' field. The language offline message uses the value defined in the site language ini file.
- Custom Message: The custom offline message will be used if the 'Offline Message' field is set to 'Use Custom Message'.
- Offline Image: Select or upload an optional image to be displayed on the default offline page. Make sure the image is less than 400px wide.
- Frontend Editing: (Modules & Menus/Modules/None). Select if you want inline editing for modules and menu items (support may depend on your template).
- Default Editor: (Editor - CodeMirror/Editor - None/Editor - TinyMCE). Select the default text editor for your site. Registered Users will be able to change their preference in their personal details if you allow that option.
- Default Captcha: Select the default captcha for your site. You may need to enter required information in the captcha plugin.
- Default Access Level: (Public/Guest/Registered/Special/Customer Access Level (Example)/Super Users). Select the default access level for new content, menu items, and other items created on your site.
- Default List Limit: (5/10/15/20/25/30/50/...). Sets the default length of lists in the Control Panel for all users.
- Default Feed Limit: (5/10/15/20/25/30/50/...). Select the number of content items to show in the feed(s).
- Feed Email Address: (Author Email/Site Email/No Email). The RSS and Atom newsfeeds include the author's email address. Select Author Email to use each author's email (from the User Manager) in the news feed. Select Site Email to include the site 'Mail from' email address for each article.
- Block FLoC (Yes/No). Whether or not to support the FLoC method of user tracking.
- Site Meta Description: Enter a description of the overall website that is to be used by search engines. Generally, a maximum of 20 words is optimal.
- 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.
- Show Author Meta Tag: (Yes/No). Show the author meta tag when viewing articles.
- Show Joomla! Version: (Yes/No). Show the Joomla! version number in the generator meta tag.
- Search Engine Friendly URLs: (Yes/No). Select if the URLs are optimised for Search Engines.
- Use URL Rewriting: (Yes/No). Select to use a server's rewrite engine to catch URLs that meet specific conditions and rewrite them as directed. Available for IIS 7 and Apache. Apache users only! Rename htaccess.txt to .htaccess before activating. IIS 7 users only! Rename web.config.txt to web.config and install IIS URL Rewrite Module before activating.
- Add Suffix to URL: (Yes/No). If yes, the system will add a suffix to the URL based on the document type.
- Unicode Aliases: (Yes/No). Choose between transliteration and unicode aliases. Transliteration is the default.
- Site Name in Page Titles: (After/Before/No). 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.
There is a complete image of the System Tab to look at if you need it.
- Debug System: (Yes/No). 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: (Yes/No). 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: (OFF - Caching disabled/ON - Conservative caching/ON - Progressive caching). 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: (Yes/No). Enable or disable platform specific caching. Enable when HTML output on mobile differs from other devices. (Default disabled.)
- Cache Time: 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: (File System/Database/Others). 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: Auto log out a User after they have been inactive for the entered number of minutes. Do not set too high.
- Shared Sessions: (Yes/No). When enabled, a user's session is shared between the frontend and administrator 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".
There is a complete image of the Server Tab to look at if you need it.
- Path to Temp Folder: Please specify a writable folder to store temporary files.
- Gzip Page Compression: (Yes/No). 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: (None/Administrator Only/Entire Site). 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: (Universal Time, Coordinated (UTC)/Abidjan/Accra/Addis Ababa/Algiers/Asmara/...). Choose a city in the list to configure the date and time for display.
- Enable CORS: (Yes/No). Enable Cross-Origin Resource Sharing (CORS)
