I absolutely love the YARPP.
Since upgrading wordpress, the plugin causes my sidebars (two, on the right) to appear below the main post. This only happens in I.E. 7; firefox hasn't had any problems.
I am using the Dilectio Theme with the most recent wordpress upgrade.
Unfortunately, I had to deactivate the plugin so I can't link to it. I can send screen if I knew where to send them!
