Word Press: Briefly unavailable for scheduled maintenance.

 

Issue:

While Updating a WordPress plugin, WordPress is automatically placed  into maintenance mode. Event Message is displayed to alert visitors of the  current system state.

Event Message:          

“Briefly unavailable for scheduled maintenance. Check back in a minute.”

Severity:

Low

Root Cause:                

WordPress generates a .maintenance file into website’s installation root directory. Usually, the plugin installation is successfully completed and then WordPress automatically removes the .maintenance file.

Solution:                    

The Event message means the automated process has failed and so, you   must manually remove the .maintenance file.

Step by Step:  

1. Log into the Web Server as user with administrator privileges.   (How to Log on to a Web Server via FTP or CPanel)

2. Locate root of WordPress installation.   (How to locate Web Server root directory)

3. Locate file: .maintenance

4. Delete file:  .maintenance

5. Refresh WordPress Website.
