I had the same problem trying to log-in to modify the page. A had the 500 error once or twice, but on the third try, or so, it just starting chugging to hook up. I let it sit in a tab, and let it do it's thing for a few minutes, and it finally logged in. I guess if you can get past the error, and get a hookup try, it will eventually work.
Edit:
Go back to my first post, and hit the link. I just tried, and it got me to my page, and I was able to log in this time.
