The System tab contains options that relate to sessions, error handling, default user, media settings, and more.
- Secret Word
You don’t have to worry about this or change it. It is used internally for encrypting things like passwords.
- Path to Log Folder
This is the path to the Joomla log file where errors are recorded. This path is set by the installer.
- Enable Web Services
Setting this to Yes will allow external applications to make remote procedure calls (RPCs) to Joomla through XML. This can be used for external applications such as blogging or site management tools.
- Help Server
When you choose which server to pull help files from, you are also setting which language to use for help.
- Allow User Registration
If set to Yes, users will be able to register on your website.
- New User Registration Type
When someone new registers, they are set as Registered by default. If you want them to be part of another access group, you can change it here.
- New User Account Activation
Setting this to Yes will force new registrants to click a link in a confirmation email to activate their account. This prevents people from using fake email accounts or an account that doesn’t belong to them.
Note
Very rarely would we recommend someone not using this feature. Occasionally, it can be a hassle when the activation email goes into someone’s spam folder and you have to manually enable the user’s account. The alternative is the potential for a lot of spam and bogus registered users on your website. The benefits usually outweigh the costs of not enabling this feature.
- Frontend User Parameters
Registered users can log in to the frontend of the website and modify several preference settings like language, editor, and time zone. If this is set to No, they will not have those options.
- Legal Extensions (File Types)
When uploading files with the Media Manager, this field tells Joomla what extensions to allow. You can add new extensions as needed, but be sure to add both the lowercase and uppercase version of the extension, separated by commas, and avoid spaces. Generally, you wouldn’t allow users to upload scripts that might be accessed by a third party to execute code on your server.
- Maximum Size (in bytes)
This is the largest file size users with upload permissions can upload.
Note
If you run into an issue where you can’t upload a file smaller than the maximum size, look at the System Info under the Help menu item in the top menu. It’s possible that the upload_max_filesize in PHP is set to a smaller number. To fix this, either edit PHP’s php.ini file or contact your host.
- Path to Media Folder
This is the path to the media folder. It is recommended that you do not change this setting, as some third-party extensions rely on this being the default path.
- Path to Image Folder
This is the path to the images folder. It is recommended that you do not change this setting as some third-party extensions rely on this being the default path.
- Restrict Uploads
This allows you to restrict uploading of nonimage files to users with access to the site’s backend.
- Check MIME Types
The MIME type will be analyzed on each upload if set to Yes. Also known as content types, MIME types define media and how it is handled by the Joomla uploader.
- Legal Image Extensions (File Types)
Separated by commas, the extensions listed here are legal image formats for those who are not restricted from uploading them.
- Ignored Extensions
Lists the extensions that you want the uploader to ignore.
- Legal MIME Types
Separated by commas, these are the MIME types that are allowed.
- Illegal MIME Types
Separated by commas, these are the MIME types that are not allowed.
- Enable Flash Uploader
This will enable a much sleeker way to upload files in the Media Manager using the Flash uploader. This also allows multiple files to be uploaded at once. If set to No, a single file input form field will be used.
- Cache
Turning on the cache can help speed up sites with lots of traffic by reducing the number of MySQL queries and the amount of processing power needed to render and return pages. If enabled, however, changes to your site will not appear until the Cache Time has expired. This setting should not be used in the process of developing a site when many changes and testing are being done.
- Cache Time
This tells Joomla how long to cache a file. After it expires, a new cache file will be created.
- Cache Handler
The Cache Handler setting tells Joomla where to store the cache.
- Session Lifetime
After you have been idle for the given amount of time, the system will automatically log you out.
Warning
Although it is tempting to make this a really large number so that you never have to worry about being kicked out in the middle of writing a long article, it truly is bad practice and a security risk. This is especially true if you will be accessing your site from public computers.
- Session Handler
The Session Handler setting tells Joomla where to store user session information.
