How to Fix Briefly Unavailable for Scheduled Maintenance Error in WordPress?

The ‘Briefly unavailable for scheduled maintenance’ error occurs when the WordPress site fails to finish an update process. This can happen while you are updating your WordPress core, plugins, or themes. Now, that you are facing this issue, your website will be stuck in maintenance mode.

Before trying to find out the solution to fix this error, you need to clearly understand the error first. In this article, we will help you in understanding the error and then we will discuss the method to solve the ‘Briefly unavailable for scheduled maintenance’ error in WordPress.

Causes of the WordPress Maintenance Mode Error:

The WordPress maintenance mode page is a notification page that is used to display the notice “Briefly unavailable for scheduled maintenance. Check back in a minute.”, while being in the maintenance mode.

During an update, the maintenance mode notification is triggered. When triggered, a temporary .maintenance file is created. You can locate this file in the root folder of your website. Now that the maintenance mode is on, the “Briefly unavailable for scheduled maintenance. Check back in a minute” notification will be displayed for some seconds. A successful update will ultimately lead to disabling of the maintenance mode. The maintenance file will be, thus, automatically deleted.

Until now, we have understood the process in normal scenarios. Then, the question is what happens when you get stuck in maintenance mode. To understand it simply, the issue is caused when the update script times out and the update process is interrupted. This interruption could be because of a slow WordPress hosting server response. A low memory issue could also result in interrupting the update process.

Now that the update process is interrupted, the maintenance mode is also stuck. Your WordPress website is, thus, not able to get out of the maintenance mode. The automatic disabling is not possible here. In this scenario, you will need to solve the issue manually.

Fixing WordPress Maintenance Mode Error:

To fix the WordPress maintenance mode error, you need to get your website out of maintenance mode. To do that, all you need to do is to follow the below steps carefully.

  • Locate the .maintenance file in the root directory of your website.
  • Use FTP to delete the .maintenance file.

  • Set your FTP client to show hidden files if the .maintenance file is not visible in the root folder of your website.

To show hidden files in Filezilla,

  • Click on Server » Force showing hidden files.

  • You can easily locate it in the menu bar.

To delete the .maintenance file from the file manager, without using FTP

  • Go to your WordPress hosting control panel.
  • Go to the file manager.
  • Delete the .maintenance file from the file manager.

Ensure that the .maintenance file is successfully eliminated. The maintenance mode will then be disabled. The error should not regenerate after this.
