Today while performing a WordPress upgrade on another blog the update failed! Grrr. If that wasn’t enough of a problem, when I checked the site it was stuck in “Maintenance” mode – meaning that no matter what you tried to do the only thing that showed up was a page telling you the site was in “Maintenance Mode”.
I Googled like a madman, and searched the WordPress site too, but there is no documentation as to what to do to get it out of this mode! So, I fired up my FTP browser and manually performed a complete upgrade of WordPress. Still no luck!
Next I checked the .htaccess file to see if the system had added some sort of line to it, but no luck. Finally, I noticed a strange file in the root of the site called .maintenance. The date stamp was just minutes old, so I deleted it and VOILA, the site was back to normal.
So, if you are unable to load WordPress because it’s stuck in Maintenance mode, just FTP into the root directory and delete the .maintenance file. Too bad this wasn’t documented somewhere, and too bad that with this in place you can’t even access the WP Admin area. Sheesh…
