Can no longer log in after upgrading.

10 years ago
I upgraded from 1.30 to 1.40 and now whenever I try to log in, I just get redirected back to the main page but I'm not actually logged in... I can't get to my admin screens at all.

ok this is odd. I switched from IE8 to FF3.x and logging in works fine... it recognizes me. I trying clearing everything out of IE, but no luck... I still can't log in that way.

Thoughts?

I've tried this on 3 browsers, IE8, FF and Chrome.

FF and Chrome work fine. IE8 does not actually log me in. It's not just my machine either, I've duplicated this problem on another machine.  

Any thoughts?
