When I try to auto upgrade to 3.4.1, I get locked out of my admin page, and have to restore the old files to get back in.
After going through this process several times, I narrowed the "problem" folder to the wp-includes, and then the problem file to version.php
If I upgrade, then restore only this file, then I can access my dashboard again. I've checked mySQL (5.0) and PHP (5.2.4) versions and they are at recommended versions or above.
I'm not sure what this means, or what I am supposed to do to be able to upgrade.
Any help would be greatly appreciated.
