CMS HELP!! Upgraded from 4.0.1 to 4.0.2 PL1 - Stories in sections no longer "flowing up"!
 

I've been posting lots of stories in lots of sections; all of those stories have "flowed up" and appeared on the front page. I just upgraded my installation and suddenly stories are "sticking" to sections.

How can I fix this?? I want the stories to continue to flow up! Suddenly the front page of my site only has a small fraction of the stories that it had five minutes ago.

Help!
