I have no idea. I've been going back and forth with them all day, and they're no help at all. They just keep telling me that they don't help with custom coding (vbulletin), that they can only help if its a server-related problem. This just started happening yesterday, and I havent done anything to any of my forums in weeks. They keep saying they havent made any changes to the servers.

This really sucks, it's obviously a problem on the host's end, but they won't help at all.

Well, I clicked 'yes' under "Add No-Cache HTTP Headers" in the options, and so far it seems to have worked for now.
Any idea why I would have to do that all of a sudden? Is there a downside to having this on?
