Post data not showing up

I have a theme that I created for one site. Then the person that I did that site for wanted a second site with the same theme except for the header to be slightly different. No problem, I just change the image for the header.

However, and this was before I changed the header so I know that didn’t cause the problem, the Posts data is not showing up. If I go to the blog page, here, I see a summary of the blog post but the title, author, date etc doesn’t apear. It should be the same as it is here

Anyone have any ideas what I did wrong? I tried to reinstall the theme a two times and still have no luck. I copied the theme’s folder via FTP from one site, to my computer so it was exactly the same then FTP’ed to the other site.
