RSS Feed Stuck & Does Not Show Up

Looking for someone to fix my Rss feed. My current site had the rss feed block inactive and now when I activate the block one of two things happen:

1. The block  shows up on the intended pages but it is giving the indication it is stuck or and hour glass as if it was waiting to be loaded.

2. The block shows up in the admin but not on the intended pages,

Help is much appreciated.
