Briefly unavailable for scheduled maintenance. Check back in a minute.– The WordPress maintenance mode
This message will automatically appear on your website when you update your plugins, themes, or WordPress.
Normally, this so-called “WordPress maintenance mode” disappears after the updates are completed. Unfortunately, it happens from time to time that the maintenance mode is still there even after the updates are done and your website therefore is not reachable.
Since you can no longer log into the backend, it is easy to lose your head. But don’t worry, your website isn’t gone and this bug is quickly fixed.
Fortunately, it is very easy to exit maintenance mode. All you need is this guide and your FTP credentials.
