In Firefox, at least, all the pages on this site are displaying in a strange way. Each page has a left sidebar with internal links and a right sidebar with sponsors. But the main content for each page only starts to appear *below* the end of the longer of the two sidebars. Unless and until you scroll down past the sidebars, each page appears void of content.
