Where is your Aviator from over at the RS board?
Yeah moving servers can do it. Sometimes you just don't get everything in the right place or forget to re-upload something.
It is important to backup your server regularly. If you have telnet access you can make one big tarball of everything and then download it to your desktop machine. This also makes moving servers much easier since you only have to upload one file.
If your site is contained in a directory called web you can telnet in one level above it and type this,
tar -cf - web | gzip > web.tar.gz
This will make one compressed archive called web.tar.gz that you then download to your local machine. I do this a few times a month for each of my servers. My host has been rock solid, but shit happens so I sleep better doing this.
Back to your problem, what is the address that is on the shit list?
