Did you do anything in Theme Designer?

The .background-dynamic class no longer exists.

Try this: .skin-oasis { background: url("http://images.wikia.com/privatematters/images/b/b3/Cartoon_Network_Wiki_Background_-_Checkerboard_%28Medium%29.png") no-repeat fixed center center / cover transparent !important; }
