ACP No Save Settings Issue
 

I've recently moved servers from a shared to a VPS. My host looked after the transfer. Everything functions as it should, or so I thought. Within the admin control panel the settings appear to function, the radio buttons move when selected, hit the save button and the redirected says "settings save" or something to that effect. Problem the saved settings have zero affect. For example, I turned my forum off, and it's still on. I thought I would disable plug-ins globally to see if that was the issue, can't shut them down, as a test I tried to make a change to one of my forum titles, it saves it within the ACP but no effect on the forum homepage. Now I can make changes within the template system but that is pretty much it. Any ideas? Here is what I've done so far...repair/optimize tables, Problematic Webserver Modules show no errors. All file permissions are 644.
