How do I enable maintenance mode in Joomla 5 or 6?

Open System → Global Configuration → Site tab, set Site Offline to Yes, set the message, then Save. The administrator stays online.

Is Site Offline the same as maintenance mode?

Yes, for Joomla. The product name is Site Offline. Searchers say maintenance mode. It is one switch.

Can visitors still log in when the site is offline?

Only groups with Offline Access (and users who can already use the backend). Registered, Author, Editor, and Publisher cannot, unless you change Permissions.

Does Site Offline hide the Joomla administrator?

No. /administrator/ stays available. Use host-level directory protection if you need to hide that too.

Why do I still see the live site after setting Site Offline to Yes?

You are logged in with access, or cache is serving the old HTML. Use a private window and clear Joomla plus CDN cache.

Can I change the offline page HTML?

Yes. Put an override in a child template. Do not edit core PHP. See Joomla child template .

What if Global Configuration will not save?

Make configuration.php writable long enough to save, or set public $offline by hand, then lock permissions down again.
