Since WordPress 3.7, automatic updates for minor versions have streamlined site management. However, on shared hosting, slow servers or low memory can cause updates to time out, leaving your site stuck displaying the "Briefly unavailable for scheduled maintenance. Check back in a minute." message. As experienced WordPress administrators, we've helped countless sites recover—follow our proven steps below.
The maintenance mode isn't a glitch—it's intentional. During updates, WordPress downloads files, extracts them, and temporarily locks your site to prevent conflicts, showing that brief notice. Normally, it lasts seconds. But if the process interrupts due to server timeouts or resource limits, the site stays locked.
First, ensure WordPress fully updates. Interrupted updates cause issues on exit. Use FTP to manually update—see our detailed guide on updating WordPress via FTP.
Next, connect via FTP and delete the .maintenance file from your site's root directory. (Enable hidden files in your FTP client: In FileZilla, go to Server » Force showing hidden files.) This file signals maintenance mode; removing it restores access instantly.
To avoid the default message and impress visitors, create a branded maintenance page. Before major updates, manually enable maintenance or use this method:
1. Create a file named maintenance.php in your site's root directory (not wp-content).
2. Add custom HTML like this:
<h1>We're updating our site—back in 30 minutes!</h1>
Style with CSS for a professional look. WordPress prioritizes this file during updates, giving a polished experience without plugins.
This approach has reliably resolved the issue for us and our clients. Questions? Drop a comment below—we're here to help.
