How to display a link in the footer section

If you look in the plugin’s directory plugins/wpmp_switcher/wpmp_switcher.php on line 53 you will see this:

add_action('wp_footer', 'wpmp_switcher_wp_footer');

so you can either remove this action and call it in your theme your self with:

remove_action('wp_footer', 'wpmp_switcher_wp_footer');

or you just make sure that wp_footer(); is inside your wrapper>footer divs.
