How can we remove the /wp-includes/js/comment-reply.js?ver=20090102 script tag?
2 steps:
first edit wp-includes/functions.php, add the follow code at the end of functions.php:
function clean_header(){
wp_deregister_script( 'comment-reply' );
}
second, edit wp-includes/default-filters.php, add the next line at proper place:
add_action('init','clean_header');
