// Are we showing debugging for templates? Just make sure not to do it before the doctype...
if (allowedTo('admin_forum') && isset($_REQUEST['debug']) && !in_array($sub_template_name, array('init')) && ob_get_length() > 0 && !isset($_REQUEST['xml']))
{
echo '
<div class="warningbox">---- ', $sub_template_name, ' ends ----</div>';
}
