wah postingan lama nih mbak rini, kl di wp271 ada dibaris ke 2173. tapi model querynya udah beda gk kayak dipostingan atas.

pada baris ke 2173 scriptnya gini :
$query = “SELECT * FROM $wpdb->posts $join WHERE (post_type = ‘page’ AND post_status = ‘publish’) $where “;

nah coba replace dengan ini :
$query = “SELECT * FROM $wpdb->posts $join WHERE (post_type = ‘page’ AND post_title != ‘privacy policy’ AND post_status = ‘publish’) $where “;

semoga berhasil ya, kl error kabarin ok
