Forbidden
You don't have permission to access this resource.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

I get this message frequently, but not always, when I go to "First unread" in the "Views from the C-Nile" thread. Doesn't happen anywhere else. If I completely leave the website and come back it works as advertised, but sometimes, like today, I had to leave and return three times. I'm using a desktop PC/Windows.

Anybody else?
