What version bp are you running?

The directories require two files in your theme folder plugin-template.php and plugin-sidebar.php

It doesn’t look like the sidebar is being generated at all. In firebug the div for it doesn’t exist. You’ve also got two ‘content’ divs that wrap the two directory widgets. Somehow you’ve got an extra one in there.

The sidebar is generated by the fn bp_blogs_directory_blogs_content() calling do_action() and triggering the sidebar function bp_blogs_directory_blogs_sidebar(). It doesn’t seem to be happening.
