I've had this plug-in installed for months and it has worked like a dream. I noticed yesterday that it was not working at all (nothing happened on hover). I was able to play around with it and get the transparency of photo to change on hover (so SOMETHING is happening) but no pinit button appears. I have since installed my own custom button on the off chance that would fix the problem. No such luck. I also de-/ reactivated the plugin. Still not working properly. I'm using Safari as my browser and I have enabled the debug mode in my settings.
