WordPress updates and upgrades are very common, both for the core of WordPress as well as the many themes and plugins that are used. WordPress has a built in feature to set the website into “Maintenance Mode” during these updates and upgrades. While that is a great idea and quite helpful at times, it can also be a problem in the event that an update or upgrade fails. In the normal process of an upgrade Maintenance Mode is turned off once the upgrade has finished. However, if an upgrade fails, Maintenance Mode will be stuck on until it is manually turned off. Thankfully, fixing this problem is quite easy.
