Full frame theme homepage post problem

Hi! First of all, sorry for my English! I have a problem with the post style. In the front page shows the text without style (http://sziszi.com/frontpage.png) but when I click on it and show the post, it shows with it's style. (http://sziszi.com/postview.png) I can't find any settings, what can I do to correct this problem? Thanks for your help!
