Site builder not loading any pages or drop down menus

Site builder not loading any pages or drop down menus

When I log into my site builder all I get is half a screen of my background. None of the drop down menus gives any choices or do anything if clicked, and any of my pages I try to load has the same issue. The actual thumbnail when choosing the site from my sites look fine.


Please help,
David

Edit: the same happens in Chrome, Firefox and Internet Explorer, so it does not seem to be a browser specific problem

Edit2: It is also not specific to my computer.
