I get the "Operating in maintenance mode. Go online." message and the Drupal 7 site isn’t in maintenance mode.
The message doesn’t appears all the time; sometimes it goes away when I refresh the page. I cleared cache; I tested, and it is most certainly not in maintenance mode.
I checked Drupal error reports, and I get this one. (I don’t know whether it’s related.)
