[Plugin: Yet Another Related Posts Plugin] No posts display with WP 2.6.3

I just updated YARPP to the newest version and now there are no related posts are being displayed, on my posts or in the feed. I’ve tried tweaking everything but they just won’t show up. I have it default to showing no text when there are no related posts, but otherwise it does display the “no related posts” text when I put something into that field.

My site is: http://www.peanutbutterboy.com

Any ideas?
