Autoblog "not found error"

I installed autoblog on a few of my Wordpress MU sites. The plugin works on all the sites, except my site, LegallyNoted.org. While the feeds process the new posts, when a user clicks on the post, it says "not found". I re-installed it to no avail and have even tried different feeds and different wordpress themes and have received the same error message.

Please advise!
