Login Failure

A few weeks ago, one of my authors (Sparrow) said she could not save her posts.

I tried to login.

It shows the status bar at the bottom taking a LONG time to process and then I go to a blank screen with the url:

http://chromedcurses.com/bitchfest/wp-login.php

Sparrow CAN log in. I, with 2 different admin logins, cannot. I asked another author to try to login and she could not do it either. Same blank screen. She tried password retrieval and couldn’t get that to work.

So I upgraded to the new wordpress 2.2. This has not helped.

Can anyone give advice on what I need to do??
