Note: You are currently viewing documentation for Moodle 2.2. Up-to-date documentation for the latest stable version is available here: Maintenance mode.
Maintenance mode is for preventing any users other than administrators from using the site while maintenance is taking place, though it's not designed to prevent user access during version upgrades.
When users attempt to access a course when your site is in maintenance mode, they obtain a message informing them that the site is in maintenance mode. If you wish, you can create a customized maintenance mode message, perhaps stating when the site will be available again or giving the reason for doing maintenance.
Note: The front page of your site will appear as normal when your site is in maintenance mode. Users will only see the maintenance mode message when they attempt to access a course.
Setting maintenance mode
To set maintenance mode in Moodle 2.x, you need to edit a value in the database. As an alternative, it is possible to set via the command line, by calling:
php [moodledir]/cli/maintenance.php --enable
and disabled by
php [moodledir]/cli/maintenance.php --disable
