I had the same problem a couple days ago. Staff couldn't help. I came up with a solution of my own. Let me know if this works for you as well.

I uploaded my background and graphic header to the wiki. Didn't do anything with it afterwards. All I did was upload them to the wiki. Then I went into theme designer and uploaded those same images again and theme designer worked perfectly.
