RSS Feed Manager Does Not Update Correctly
 

I set it up so that my wordpress blog's RSS feed (via Feedburner) will send posts to a specific spot in my forum; however, it doesn't continuously update (even though I ask it to check every 20 minutes).

It only works if I run it manually (which sort of defeats the purpose of having it be an automatic scheduled task...)

Ideas?

The only plugin I'm using is VBseo so I'm sure it's not that.
