Hi Eric,
Not "on top" but "replacing". We need a way to tell if we are on the frontside or the backside, and I think this will do:
<?php $is_admin = strstr("http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]", osc_admin_base_url());
if (!$is_admin) osc_remove_hook('init', 'rich_edit_init'); ?>
Regards
