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.
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.
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.
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.
This is the largest file size users with upload permissions can upload.
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.
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.
Separated by commas, the extensions listed here are legal image formats for those who are not restricted from uploading them.
Lists the extensions that you want the uploader to ignore.
Separated by commas, these are the MIME types that are allowed.
Separated by commas, these are the MIME types that are not allowed.
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.
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.
This tells Joomla how long to cache a file. After it expires, a new cache file will be created.
The Cache Handler setting tells Joomla where to store the cache.
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.
