WordPress Maintenance Mode Error
Why Does The WordPress Maintenance Error Happen?
The Maintenance mode page is actually not an error. It is a process that normally happens when you are updating plugins, themes, etc. Normally if everything has worked out, then this notice will probably be displayed for only a few moments. However, sometimes due to a web server’s slow response or low memory issue the the WordPress maintenance page may timeout or be interrupted. When this happens, you website may be stuck in the WordPress maintenance mode.
