(my site) /wp-admin/
takes me to a message -Database Update Required-
WordPress has been updated! Before we send you on your way, we have to update your database to the newest version.
The update process may take a little while, so please be patient.
BUT after I click the update button I cannot get to the dashboard at all.
It seems to be a closed loop. I have tried logging out and clearing cache. what's up? I'm not fluent on the back end so this is a big problem.
