Hi, I've read through the other closed threads on this topic and tried all of the suggested remedies. I've cleared cache and browser history, disabled adblocker, etc and still the Jetpack Facebook widget is not displaying on any of my websites when I view them in Chrome.
Also, it seems to me that it's a problem if everyone visiting my site has to clear their browser history before they can see the widget. Not that this helped in my situation, I'm just saying that that doesn't seem like much of a real fix.
