I am able to view the RSS feed of my Custom Post Type. I can see new posts from the Custom Post Type on Google Reader and Facebook.
The problem is when I try to click on a featured image or the post title from the RSS feed, the link doesn't go to the post on my site. Instead, the RSS feed title opens the google website instead!
