Ok, I just uploaded the file and everything seemed to work, but for some reason your home page wasn’t showing any of the homepage widgets. So I went to Settings > Reading and saw that you had your homepage settings set to this – http://i.imgur.com/a42DITV.png
So that’s the reason it wasn’t working before. I changed it to Latest Posts so the homepage template will be activated. If you want to have a blog page, create a Page title it Blog, and then choose the Blog Template in the righthand sidebar.
Let me know if this helps.
