I'm having trouble changing the theme. When I go through the process of selecting any theme I've uploaded, it returns a blank page that thinks it's done, no source code rendered. If I switch back to any of the 'classic' themes, like MU Home Default, for example, everything is visible again.
Also, the non 'classic' themes had to be deleted before I could bring back the MU Home Default.
So, something is not right, but I'm not finding where. Any ideas?
