Facebook Share Problem

Hi guys, fantastic job with the plugin 😀

btw, recently, I encountered a problem with facebook share button. When i click the button, instead of popping up a small window , the button lead my me to another link (https://www.facebook.com/sharer/sharer.php?s…..)
Is it a bug ? How could i fix it?
