Why do I constantly receive this (page specific) error? It usually goes away after a day or two, but if it is occurring on the last page of a thread it keeps me from responding meaningfully, and in any case, it keeps me from knowing what people are saying.
Edit: after composing this question and hitting post, I received the HTTP 403 error preventing me from viewing my own post. I exited, then reentered and got an HTTP 403 error when I tried to access this forum.
