How to Fix Briefly Unavailable for Scheduled Maintenance Error
Briefly unavailable for scheduled maintenance. Check back in a minute. Maintenance mode page is not an error. It is a notification. During the update process, WordPress downloads necessary update files to your server, and replaces older out of date files.
Once you have updated WordPress, all you have to do is find and delete
.maintenance file from your site’s root folder (httpdocs folder) using FTP. If you can not see .maintenance file in your site’s root directory, then make sure you checked your FTP client to show hidden files.
In Filezilla, you can force it to show hidden files by clicking on the Server » Force showing hidden files from the menu bar.
WordPress creates a
.maintenance file during the update process which indicates that your site is in the maintenance mode. Unless this file is removed your site will remain in the maintenance mode and your users will continue to see the notification.
Follow the steps above and your website will be visible to the public straight away.
