[Plugin: Social Media Tabs] Facebook and Google 1 not working

Facebook shows a blank area (correct facebook ID was used. I used the custom and then the original numeric ID, both don’t work).

Google +1 displays and error pop-up that says “The URL is not valid and cannot be loaded” whenever you click the 1 week, etc. links. (Correct ID is used, and there is content available). I should note, that when hovering over the 1 week link, for example, the URL at the bottom of the browser screen displays “http:///”
