im having some issues with installing the upfront themes on a new wordpress,
the background images don't appear at all, and the layout of the front page is collapsed to the left.

i have 3 accounts on this server all doing the same thing, i have previously installed themes on another account and they are working, just not the new installs
i enabled debugging
