I'm also getting those login problems anywhere but the main page in the uppermost login section {the one below it doesn't like to work either}.

I also had a problem deleting PMs. I kept going from the Private Messages link/dropdown in the Welcome, Khatovar box, but I couldn't get to where the supposed PMs were. Tried to delete them from where that link takes me, got confirm dialogue but they were still there. Tried from the User control panel, still wouldn't work. I had to go in though my profile. This may just have been old PMs, though, since I can't duplicate it with new test messages I send myself.
