Why Does WordPress Maintenance Mode Error Occur?

The WordPress maintenance mode page is technically not a bug. It’s a notification page.

During the update process, WordPress downloads the necessary update files to your server, extracts them, and then installs the update.

WordPress also puts your site in maintenance mode and displays the message “Briefly unavailable for scheduled maintenance. Come back in a minute. notification during the process.

To enable maintenance mode notification, WordPress creates a temporary .maintenance file in the root folder of your website.

If everything is working normally, this prompt may only appear for a few seconds. Upon successful update, WordPress will automatically delete the maintenance file to disable maintenance mode.

Cependant, parfois en raison d’une réponse lente du serveur d’hébergement WordPress ou d’un problème de mémoire insuffisante, le script de mise à jour expirera et interrompra le processus. Lorsque cela se produit, WordPress n’a pas la possibilité de sortir votre site du mode maintenance.

En d’autres termes, votre site affichera toujours l’avis de mode de maintenance et vous devrez le corriger manuellement.

¿Cómo reparar el error del modo de mantenimiento de WordPress?

To get your website out of maintenance mode, all you really need to do is delete the .maintenance file from your site’s root folder using FTP.

If you can’t find the .maintenance file in your WordPress root directory, then make sure your FTP client is set to show hidden files.

In Filezilla, you can force it to show hidden files by clicking on Server » Force showing hidden files from the menu bar.

Once the .maintenance file is removed, your site will come out of maintenance mode, and the error should be fixed.

If you don’t know how to use FTP, then you can also remove the files by going to the file manager in your WordPress hosting control panel, and then deleting the .maintenance file inside the file manager.

How to Avoid WordPress Maintenance Mode in the Future?

We already know that the “Briefly unavailable for scheduled maintenance” error is caused by slow server response or low memory issue on your web hosting server.

The easiest way to avoid this error is by upgrading to a higher hosting plan. We recommend going with one of these managed WordPress hosting companies that offer superior hosting performance.

If upgrading to a higher hosting plan is not an option, then we recommend doing plugin and theme updates one at a time.

Often users have a tendency of quickly clicking on the update link underneath each plugin. WordPress then staggers the update order, but even a millisecond of delay in connection could cause a conflict leading your site to be stuck in maintenance mode.

Instead of quickly clicking on the Update link, we recommend patiently updating one plugin at a time.

How to Customize Maintenance Mode Notification

An easier solution to avoid showing the default maintenance mode notification is by manually putting your WordPress site on maintenance mode before installing any updates.

The best way to do this is by installing and activating the SeedProd plugin. It is the most popular maintenance mode plugin for WordPress. You can customize your maintenance mode page using the drag and drop builder and integrate different email marketing tools.

First, you’ll need to install the SeedProd plugin on your website. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, go to SeedProd » Pages from your WordPress admin panel and click on the ‘Set Up a Maintenance Mode Page’ button.

Here are some additional steps you may need to follow if the above solution does not work.

Is WordPress still stuck in maintenance mode after the above update and fix?

If so, you need to update the wp-activate.php file located in your main WordPress folder. This is the same location where you found and deleted the .maintenance file.

You will need to open the file with your hosting provider’s file manager or upload it to your computer via FTP.

Then you need to find the code: define(‘WP_INSTALLING’, true) and change the true to false.

So your code will look like this:

set(‘WP_INSTALLING’, false)

After that, you need to save the changes and upload the file to your hosting server via FTP. If you’re using the host’s file manager, just save the file to exit maintenance mode.
