Sidebar problems

Using the tech-blog theme…have a problem with my sidebar in the “pages” part. the sidebar falls to the bottom center of the page. The “pages” category was orginally commented out in the sidebar.php file. This probblem only occurs in the “pages” section.

here is an example…

Any help or direction on where the problem might exist would be greatly appreciated. Thanks1
