k2 item fb like & share buttons disappeared after upgrade

If I use Facebook's Like Button configurator at developers.facebook.com/docs/plugins/like-button#configurator and put in your URL, there is no like button rendered there either. Looking at your source, the FB javascript is initialized properly and we're passing everything in correctly to FB, but what comes back is not rendering. I think you need to submit a bug report to Facebook.
