I don't know if it's me but I am having issue with log in, after entering my log in info; the next welcome message pop up, then redirect me back to the front page and still show that I am not log in.
I had to login once after the change but I had no problems doing that; I think there was a check-box about remembering who you are when you login. If that isn't working you might want to clear/check your cookies or cookie settings.
