Theme not installing correctly

It appears your installation is not loading the appropriate stylesheet. What method did you use to install the theme? Also, did you download the theme from wordpress.org? If not, unfortunately, you will not be able to receive support here.

From looking at the site you said it’s supposed to look here, the active theme there looks to be a child theme of the Twenty Twelve WordPress theme. I know wordpress.org does not distribute child themes. Where does your theme come from?
