That error page has been reported by another user previously and is most likely a security token issue of some kind. It seems to believe there is some type of cross site script exploit and is blocking the action.
Basically everything we're talking about here will only likely iron itself out if I re-install the site software I think. This would have been easy had that 3rd party addon not fucked things up beyond all repair.
If you guys can just bear with it a while longer I'll endeavor to get a test site up and configured in the next week or two.
My sincerest apologies folks, these are all issues that are somehow a direct result of moving to a new Server, Server config or something, not sure? There is just so much information on what it can be that I have no idea where to start at this point?
It's just better to wipe, start fresh and troubleshoot on a clean install.
This way at least we alleviate the software approach to most (if not all) problems.
Then it points to either server, db or both.
