so a few weeks back, I switched my boards to use an add-on domain (from robkamphausen.com/ubbthreads to rkmbs.com). Everything seems to be working fine, but on occasion, some posters are getting the following:
"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. "
Any idea what I did wrong...?
