My problem was furni, it was set to the right link but it was my ip (1.2.3.4/gamdata.. etc)
I changed it to my domain and it worked.
Weird issue because the Domain points to the IP, so its essentially the same thing.
and yes, your vars.
Your links are incorrect.
Clear your cache after updating links.
I had a similar issue, I thought the links where right, but they were not.
Keep looking.
Fed up of looking at my files, I've missed something somewhere, can anyone see something wrong?

Yes I gave you an IP, woo, its a test server.
