Hmmm.. are you adding that tag manually, or is that coming from using our Content plugin, which automatically adds the social buttons to articles? If you're adding it manually (which makes sense, since the link isn't pointing to your site), check the following:
* The JFBCSystem plugin is enabled (I know you already said it was, but still have to say it)
* The System - Cache plugin (if enabled) is ordered after (higher number) the JFBCSystem plugin
* If you've set an Admin Render Key in the Social -> Misc tab, included that key in the tag like {JFBCLike key=XYZ ...}
If none of that helps, let me know what page I can see that on, and I'll do what I can to help further. You can private message me the full link, or just send the relative URL. I already have your actual domain since you ran Autotune.
Glad to hearing you're enjoying JFBConnect! There's definitely a lot to it, but we're always trying to add features and make things simpler in general. If you ever have any feedback/suggestions, we'd love to hear it!. For Twitter, we're hoping to have a something out in late summer. It's still in the very early phases, so that could be pushed back anytime until the end of the year...
Thanks,
Alex
