JFBCFriends not working

I honestly don't know what's going on there. I'm seeing the same issue if I use the configuration tool on Facebook:
developers.facebook.com/docs/reference/plugins/facepile/

Let me look into it a little further, but unfortunately, I don't have any suggestions right now. Feel free to play with the configuration tool using different URLs to see if something works or if there's a trend for ones that don't.

You're in the right area In that section, if you don't want it to show in the articles themselves and just the category, set "Article View" to Hide. That should be all your looking for, as those settings configure what types of views the Likes/Comments will show in (Article Views, Category Views, Front Page Views, etc). Then, the settings below that allow you to specify the specific articles within those views that will actually have the Like button or comment box.

Hope that helps explain, and if you need something else, just let us know

Also, in the future, please create a new topic if the question is unrelated to the original.

Best of luck,
Alex
