URL Forwarding

Hi everyone,

I hope someone can help me. I am forwading my domain address to a folder on a different host. Everything works fine with wordpress but the particular theme I am using, some of the functions stops working in IE and it gives error “Access denied” but the theme works fine when I load it from the domain which is connected to the host that the theme is located on. when I change the wordpress blog URL to the forwarding domain everything crashes so that has to stay as the original domain link. I think the theme double checks the domain is being viewed from with its own actuall address. Does anyone know how to fix this issue or where in theme functions should I change to stop this double check?
