Just looked in my source code and see another andsense code on my site. How can I block other adsense codes from being on my site?
How it can be true..? is somebody else has the access to your website - if not then how can it be replaced on its own...
Just delete it simple. I think you must have bough some template script or bought the whole site itself. thats why you are seeing other people code.
Unless someone has access to your server and hosting, the cannot hijack your ads like that. the only other way is if there is some software on your machine or browser that is embedding their code into all sites with adsense that you visit
Option one: delete Option two: block site in Adsense console Option three: forget Adsense and move on to more profitable options
