Blog posts and 404

Hey, there,

I recently developed a site on a mirror site then when I activated the regular site, my blogs started getting 404 not found.

I exported the blogs from the mirror site and imported to new site but still getting 404.

The blogs are there – if you go to their index page you’ll see them:
http://www.bigtentdigital.com/sideshow/

it’s when you click through to the individual blog you get the error message? Any suggestions? The URL’s are matching the permalinks so i’m not sure what’s going on.
