Layout and images not displaying correctly

I am currently creating a Intranet page for the school I work at, the theme is ideal for providing quick links to other pages so that students can simply click on the site they want to go to as opposed to typing it out or searching for it. However whenever I preview the site it only has one column and rather that the faded blue circle over the featured image it has a solid blue square. Both my Java and flash versions are up to date, as well as all my WordPress plugins and theme versions.

Any help with this would be greatly appreciated.
