Yesterday, I decided to revive my blog, and to update it with the last version of WordPress.
It took me a while to do so, as I encountered a few problems.
Eventually, I succeeded in completing the update. But I've since discovered that everythime I try to log in, and no matter what account I use (even by using the Admin account), I get this message : "You do not have sufficient permissions to access this page."
What did I do wrong, and how can I solve my problem ?
Everything has been backed up, so I'm confident I can return to the old version if I don't find a way to have this 2.0.4 work.
