Many WordPress users have faced a frustrating situation where they try to update a theme or plugin, but the process gets stuck, leaving the website in maintenance mode.
When this occurs, a message appears that reads:“Briefly unavailable for scheduled maintenance. Check back in a minute.”
Why This Error Appears
During the update process, WordPress creates a temporary file named .maintenance in the root folder. If the update finishes normally, that file is removed. However, if the update process is interrupted, the file remains in place, causing the website to stay in a perpetual updating state.
This issue often happens because a browser tab is closed in the middle of an update, or too many plugin or theme updates are run at once.
When you click the ‘Update’ button for all your plugins at once, WordPress is set to update them in order, one after the other, with no time gap between the updates. Now, even a tiny delay in the connection can lead to conflicts and get your site stuck in maintenance mode.
The Fastest Fix
In most cases, the fix is simple. Connect to your site through your hosting file manager, or SFTP, go to the WordPress root folder, and delete the hidden .maintenance file. Once the file is removed, the site should load again instead of showing the maintenance message.
What to Check Next
After the site reloads, log into WordPress and check the update that failed to complete. WordPress might display an admin notice informing you that an automated update failed and needs to be retried.
When the File Is Hard to Find
The .maintenance file is usually hidden, so you may need to enable “show hidden files” in your host’s file manager or FTP client.
Whether you’re working locally or on a managed host,the same rule applies: find the site root, uncover hidden files, and remove the .maintenance file. If you can’t access your files directly, your hosting support team can usually take care of it for you.
How to Prevent It Next Time
Most of the time, this problem stems from a lack of server resources.
If you find this problem happening regularly, upgrading to a better or larger hosting plan could be a solution.
If upgrading is out of the question, a safe workflow could be to back up the site first, and then update one plugin or theme at a time. That reduces the chance of getting stuck again. Another best practice to follow is waiting for each update to finish before leaving the page. That routine is simple, but it prevents a lot of stress.
Final Thought
This WordPress error may seem serious, but it’s often just a temporary maintenance file that hasn’t been removed. Simply delete that file, check the update that failed, and proceed with caution.
