WordPress提示Briefly unavailable for scheduled maintenance. Check back in a minute解决办法

Today, while upgrading a WordPress plugin, I encountered the message „Briefly unavailable for scheduled maintenance. Check back in a minute„, which translates to “Routine maintenance is in progress, please come back in a minute.„ However, the entire website became inaccessible. Since this wasn“t the first time I„ve faced this issue, resolving it was straightforward.

Methods to resolve „Briefly unavailable for scheduled maintenance. Check back in a minute“

The root cause of this prompt is that WordPress automatically generates a .maintenance file during the upgrade process to prevent website access while upgrading. This file is automatically deleted upon successful upgrade completion. However, if the upgrade fails, the .maintenance file may not be automatically deleted. Manually deleting this file will resolve the issue.

Method 1: Delete via SSH command

Using an SSH command, navigate to your website's root directory, then enter `rm -rf .maintenance`. For a tutorial on using SSH to manage your server, please refer to:#建站#Xshell 6 Basic Tutorial: Connecting to a VPS

Method 2: Delete via Baota Panel file function

Log in to the Baota Panel Admin Dashboard, click on your website's folder, locate the .maintenance file, and delete it. Forgot the Baota Panel admin address? See:What to do if you forget the Baota Panel backend login URL

Method 3: Delete the .maintenance file via FTP

Open your FTP software (FileZilla, a free FTP client, is recommended), log in to your website's root directory, locate the .maintenance file, and delete it.

Method 4: Modify the wp-activate.php file

If you cannot find the .maintenance file mentioned above, you can try this method. Locate the wp-activate.php file in your website's root directory. You can modify it via SSH or download it locally via FTP for editing. On line 9, change `define( 'WP_INSTALLING', true );` to: `define( 'WP_INSTALLING', false);`. Then upload the file and refresh your website to regain normal access.
