I can't be sure, but this seems to have stopped working when I updated the plugin to v1.0. It never seemed to complete the upgrade, yet it shows it is v1.0. Is there a way to manually update the plugin or force it to re-update, if indeed this is the problem?
Can you please check our site at http://www.stubbydog.org?
I also had to update our theme single.php to add the "if function" statement to correct the comments section being totally screwed up.
Thank you, jim
