The problem seems to be with syndicated feeds. The feed publishes on my WP site with no problem, but when it gets sent to FB, everything looks ok until you click the link, then you get "Not Found. Sorry, but you are looking for something that isn't here."
This ONLY happens for posts from an RSS feed, because when I create a post myself, it works fine. I've tried networkblogs.com and twitterfeed and they both produce the same problem.
Maybe it's something simple I've overlooked, but I'm hoping someone can help me out with this.
