somehow you have two lines in the main column
these are comments and cause the following
HTML Code:
<div class="post-1 post type-post hentry category-uncategorized" id="post-1">
to become a comment so the info in the center never shows.
You need to look at ato->Style & edit CENTER COLUMN to see if you have made any changes and/or look at any of the theme code that you may have changed
