No Response from http://wi.likebtn.com

I am getting the following error:

GET http://wi.likebtn.com/w/i/?s=%7B%22h%22%3A%22bse2.empire-dev.com%22%2C%22s%…41719df0113f%22%2C%22957ec787ad2a%22%2C%22b6467fc7ab18%22%5D%7D&lb=lb_json widget.js:1 loadwidget.js:1 jsonpwidget.js:1 obj.loadBunchwidget.js:1 (anonymous function)

I haven’t made any changes and this was working up until yesterday.
