Uploading Theme to another host

I’m designing a site for a client using the free wordpress theme Craft Cart. The site looks great and everything is working on my sample site here: http://edubgraphicdesign.com/quiltcouture/

But the sidebars are smaller at the bottom and the gallery isn’t working on the main site here: http://quiltcouture.com/blog1/
Also, the weirdest thing is that when I move the widgets around, it doesn’t save them. I have to log out and then log in again.

She uses yahoo hosting and I use justhost…so maybe I’m thinking it’s the host, but wanted to see if anyone had any suggestions.
