Gradient settings aren’t working

On the blog I’m working on, http://corporate-blog.kachingle.com/, I have changed the upper gradient color and lower gradient color in theme options, but the colors aren’t changing.

I do see a brief blue flash behind the gradient and then the old gray is back.

Any thoughts?

(If I don’t figure this out quickly I’ll revert to an old theme so you won’t see the flash in action.)
