I'm looking to test some themes for my live site on a test server. The server is a clone of my current site and the only difference is the url. I downloaded a couple of premium themes to test so that I can figure out any issues but any theme i install doesn't seem to be accessing it's stylesheet. So the site is just a big huge unstyled page. I'm not sure if it's because i'm accessing my WPMU dashboard from a site that's not my live site or what. Any help would be appreciated. My testing url is http://ec2-23-22-8-106.compute-1.amazonaws.com/
Any themes that aren't downloaded from WPMU works fine.
