Stopped working

This plugin was working great until about a week ago. Suddenly, it stopped displaying any comments. It was working before the 4.2.3 upgrade and as far as I can tell, this plugin wasn’t upgraded recently.

When someone posts a comment, I get notified and they show up in the moderation area in FB, but won’t display on the site.

Here’s an example page. I got two comments on this page in the last few days, but nothing shows up:

Thanks!
