It seems like your gallery script is looking for two elements with the ids of caroufredsel-clients-container and caroufredsel-blog-posts-container. I don't see any errors/issues with loading in your "galleria" css or js files.
Without digging in deeper I can't really tell you how those elements get set or anything. The two sites aren't using the same scripts it seems, so I can't really sit and compare the two to see why one works and the other doesn't. So I'd have to investigate how that jQuery CarouFredSel script is designed to work since that's where the issue seems to lie.
