Step 1
Log into your Moodle site as an admin user, and navigate to the Maintenance settings option: Site administration > Server > Maintenance mode
Step 2
Click “Disable” from the Maintenance mode drop-down list.
Step 3
Click the “Save changes” button and your Moodle site is now out of maintenance mode, and accessible to all users.
If you would like assistance disabling maintenance mode on your site, please do not hesitate to reach out to the Hubken support team
