Facebook "Like" Buttons in the articles

Since yesterday the Facebook Like Button in the articles is missing. I did not chance anything in the Template- or K2 Configuration. Twitter an Google+ are Working.

Any Ideas ?

Here´s an example link

Please try to cut API ID, save settings and paste it again, then save. Please also try to change the width of buttons to 400px.
