Hello! I need to know if there could be problems with google analytics if someone else is using my tracking code in another website. Let me explain, somebody stole my wordpress template using the source code and he didn't even removed the google analytics tracking code. I found about this because I'm also using histats tracking code and that one is reporting traffic from his website. I tried to contact the webmaster but he wont answer and he haven't edit the template. So, can this cause conficts with google analytics? penalties? Is there a way to regenerate a new tracking code?
No, it will have no ill-effect on your Google rankings or any of your efforts. The only thing is that you will get inaccurate information in your Google Analytics account. In order to do away with it apply filters. Check out the IP address of the website and block it via filters.
