I just got stuck in a weird loop trying to login or access http://www.comicbookdb.com/
- Firefox presented me with some error about infinite redirections in index.php. Deleting all cookies from the site allowed me to access it again. (Unfortunately I didn't save the error message -- sorry!)
This started when I tried to login. I'd logged in previously in the day, surfed around the results of a couple of different searches, and at some point I didn't notice, the user controls in the left-hand menu were replaced with the login prompt. (Login auto-timeout?) I continued surfing until I hit a 'mature content' link, when the system's refusal to show me the link led me to discover I hadn't been logged in since my most recent search. When I tried to re-login, boom, I hit the loop.
I may be on for a while longer today; if it happens again I'll post the error and cookie contents.
