Hi Fuz
In my experience, when moving sites from LIVE server to a DEV Server issues like this were there all the time.
As I am sure you are aware, LIVE sites are configured to NOT show errors to user, but Development server (WAMPServer) of course are configured to show all errors, so they can be fixed before making the code live.
So I would start by looking at the LIVE Server logs. Do you see this error there?
