facebook like count suddenly not working any more

Hey everyone! The posts on my site https://www.alphaleonisastrology.com have all of a sudden stopped to display the number of facebook likes each post received – like it would say “person x and 100 others liked this post” previously – and now there are just the like and share buttons without any indication how any people liked the post. I am using the offical facebook plugin. Can anyone please tell me what has happened here??? Thanks a lot in advance!
