I have no other mods or plugins. It's basically straight vb4.1 with reviewpost. Even the integrated vbulletin blog is currently disabled.
Turning off the plugin makes the error go away, so it must be related to the plugin?
Plus, it was working at the old server, so I would thinkg something in the server move related to review post caused these issues, whether file paths or otherwise.
I don't mean to be difficult. This is a very frustrating plugin to troubleshoot, even for tech support at the new provider, which is why I'm here of course.
