Briefly unavailable for Scheduled maintenance

What Causes the Problem

The error message is to prevent the visitors of websites dealing with the broken pages and preventing the world or yourself from accessing your WordPress site during the upgrade process. When WordPress automatically update WordPress core files or it’s plugin, WordPress site will be in maintenance mode. This problem occurs when the maintenance process failed half way and was not complete at the end of the process. Sometimes the problem is caused by the web server response is too slow or the server memory resources shortage and update script will probably gets interrupted and time out.

Solution :

Fortunately, the solution is very easy to implement. You can simply delete the .maintenance file from the WordPress root directory or just rename it to other file name. After you have deleted a file or renamed files, you will be able to access the site as usual, but you may need to execute the automatic upgrade process again.
