Switching colors/backgrounds doesn't work in Dixi/Nelo/Triden

When I use the Theme Options to change the background colors, text colors, and other elements of the theme, it accepts the changes. When I load my site, refresh, etc. there is no change. The theme options page still shows my choices for colors, but the actual blog theme doesn't show the changes.

I have viewed from other computers, reset my browser cache, etc.. I also have just about zero plugins running.

I tried it in a local MAMP install of WPMU and it worked fine. So why isn't it working on my web server?

Anyone have any ideas?
