Sometime in January, Facebook's like box social plugin (https://developers.facebook.com/docs/reference/plugins/like-box/) stopped catering for the height attribute and it's now fixed to 300px height unless you tick the Show Faces box.
Since I would like to display a feed at longer height, I decided to make my own.
