Facebook widget thumbnails missing

[ Moved to the Fixing WordPress sub-forum. ]

Just noticed my thumbnails showing my likes from facebook are missing from the footer of the site im working on www.kentcleaningservices.co.uk

The only thing i changed recently was the facebook business name but I’ve also changed this in the widget but it still not working.Any ideas how to get the thumbnails to show again? Using Chrome and the theme is Venedor. At the bottom of the page you will see a twitter feed and the facebook section just says facebook then a black space.
