I got an email from one of our forum users:

Quote
The host from which you are accessing the board is not recognized as a valid host. This is more than likely related to a firewall issue that is blocking the referer variable. Check your firewall settings and try again.

Please use your back button to return to the previous page.

I have Zone Alarm firewall but I don't see where these variables would be changed.

Any suggestions on how best to help this person? I'm not sure what to tell her, and I don't really like to say "it's not our problem" if I don't have to.

Thanks,
Tracy
