Facebook Like Box has disappeared

When I first set up my website (www.ecclesrfc.org.uk) the facebook like box widget was working as I expected in the sidebar. I’ve noticed today that it’s not there any more! Unfortunately I can’t say when the last time I definitely saw it was, and have performed a number of updates and tweaks recently.

I’ve tried deleting it and re-adding it but it still doesn’t display. In playing with it I’ve found that if I enter a Title (which I didn’t have before) that text will display (and be a link to the facebook page) but the recent statuses and like button still don’t appear.

Any ideas
