I have installed the full demo package, and the front-end works fine. However, when I go to the administration screen of the template I get a pop-up that appears, but it doesn't have any content (see attached). It will not let you close the pop-up either. This is a draft website and I have installed it in a folder off from the main root where the present live website resides.
