I just went to update Drupal 7.5 to 7.51 and fortunately the update worked. Unfortunately our site is now locked in maintenance mode and I was logged out of the system and cannot get back in as an admin or anything on the site for that matter.
We tried to do a site rewind to go back to our original settings before the update but still no luck. We also tried using
/user and also
/?q=user but this doesn't work either. The site seems to be stuck in some sort of page refresh loop. Does anyone have any suggestions of what else we should try or what we should do?
