Adsense displaying on 404 error page

[Vivek]

Brian , this seems to be serious mistake and which could lead to many account disabled :shock: . You calling " ?php get_header(); ? " which is leading to this :?: , i noticed this while i was customizing the theme . by mistake land on 404 page. Please solve this problem as soon as possible.

Displaying adsense on non content based page ( error ) is strictly prohibited

what i can do is simply remove " ?php get_header(); ? " until you make correction

instead of calling entire header and sidebar , we can write entire script in each of them i.e header & sidebar excluding adsense :D
