Besides being banned what are the other possibilities if I get the error in Firefox that says Problem Loading Page? I haven't had the chance to go to a different house and check if me IP is banned, but I'm not even sure where I'd find that. In fact I don't know why I'd be banned in the first place. However, I know the site is up and that it works because I've asked 5 friends and seen it myself at my school. I'm not able to view anything on my server even items besides the php-nuke.

Is this a browser problem or and ban issue?

How can I solve it?
