I successfully upgraded to 3.5 but have been locked out of my Admin area after a failed database update. After upgrading I was presented with a screen requiring me to update the database:
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.
and then a button:
Update WordPress Database
After clicking the button I am presented with a white screen with the WordPress logo on top. No matter how long I waited nothing more happens. It has hung. I've tried several times.
So I have gone into phpMyAdmin and disabled all plugins. That hasn't changed the situation as when I visit http://www.mywebsite.com/wp-admin I am given the same instruction to upgrade the database.
I've tried forcing the update of the database through phpMyAdmin by changing the db_version setting to 21707 as instructed in the Codex. But this then just takes me back to the suggestion to update my database and I am back at square one with the blank white screen with the WordPress logo at the top.
Any ideas on how to get my database to upgrade without giving me the "WordPress White Screen of Death"?
