Yii Adds Smthg Like #.umejj0Jecg4 To Url

sorry for silly question, maybe its not yii, but suddenly I have noticed, that after loading page its adding some code to url something like #.UMejJ0JECG4.

Could you help me to prevent that behavior?

solution found! Its not yii its AddThis Plugin

just add "data_track_addressbar":false to config of addthis

Ha, you must have fixed it as I was checking it out. The problem mysteriously disappeared after the first 2 visits lol.
