When maintenance mode is enabled, only administrators have access to the forum. Other users will see the message "This forum is in maintenance mode". In maintenance mode, the database may still be accessed for user authentication (to check if the member is an administrator).

Administrators use maintenance mode while doing tasks such as: forum upgrades, backups, restores, installing and uninstalling themes and modifications.

2. Check the box next to Enable Maintenance Mode.

4. If you wish, you may change the Message for display. All guests and members will see this message and it can be used to give an explanation as to why the forum is in maintenance mode.

How to Disable Maintenance Mode
