Wo hast du für $rightnav gemacht, [...]
PHP-Code:
$tpl->set_file("rightnav", "mainlayout/right_navigation.tpl.html");

oder, was auch gehen müßte:
PHP-Code:
$rightnav = implode ('', file("mainlayout/right_navigation.tpl.html"));
$tpl->Insert("{rightnav}", $rightnav);

aber ohne dein tpl zu kennen ...
