I'm having trouble with my admin dashboard after upgrading to 2.5.
I can get to the admin page and login just fine. I can click on items like Write and Manage and get those pages just fine.
BUT, if I want to navigate deeper (say try to go back to earlier posts to edit) then the navigation redirects back to the main admin page.
I can manually insert "edit.php" into the returned link, though, and use that as a workaround.
Any clues how this happened / how to fix. It's rather inconvenient!
