For some strange reason, I am completely unable to get Supersized to work with the default twentyeleven theme. When I view the source of the page, everything seems to be loading correctly. But when the page renders, I just see the spinning "progress.gif" and the forward/back.png buttons. The slideshow images don't seem to be loading at all, though.
My plan is to, eventually, create a child theme based on twentyeleven. But for now, I'm just trying to get this working with a basic installation before I make any customizations.
Here are a few links to pages that are experiencing the problem:
Thanks so much for your help on this!
