Good call.
I’ve been sitting there for weeks saying “I know I have visitors, I have comments”.
I duplicated the line, figuring if I switch themes, the page will use one or the other, so cover my bases:
stats/stats.php – toward the bottom:
// Plant the tracking code in the footer
add_action( 'wp_footer', 'stats_footer', 101 );
add_action( 'get_footer', 'stats_footer', 101 );
