I have recently moved my installation of Xenforo to a new host (bluehost.com) and everything seems to of moved smoothly however no one is able to post anything. People click 'Create Thread' or any other similar button and nothing happens. The screen shows the little loading bar and then disappears, nothing appears to happen at all.
I've made sure that all the requirements have been met to run Xenforo but other than that I'm a bit lost at what to do.
EDIT: Looking in the console on Chrome I see this error:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
