Howdy. It looks like it was the Share button. I removed the inclusion of it in the "Content - Article Footer" plugin, which was inserting it in the bottom of every article. We're sorry the Share button doesn't work, and will hopefully have a better solution soon.
In the meantime, if you'd like to automatically include the Like button and Comment module, you can use our JFBCContent Plugin which allows you to automatically insert these Facebook widgets at the top or bottom of every article. For more information, see our blog post:

Good luck, and let us know if you have any other questions!
