Upgraded WPMU and some blogs posts not showing – random chaos here!

Just upgraded to WordPress MU – and all of a sudden some of my blogs are not showing their posts…even though the accurate post count shows on the dashboard – the post titles show in sidebar recent posts widgets etc. It’s not every blog – just random ones throughout the site.

I use this for our school district and desperately need help!

URL of our site – http://blogs.burlesonisd.net/

URL of a blog with no posts – http://blogs.burlesonisd.net/kingsblog/

Please help!
