No it doesn’t. The post editing interface still show up, only that it has the error message at the top.
For now, I’ve changed the code to check whether the nonce is empty:
if (empty($_POST[‘wti_like_post_meta_box_nonce’])
|| !wp_verify_nonce( $_POST[‘wti_like_post_meta_box_nonce’], basename( __FILE__ ) ) ) {
return $post_id;
}
Not sure if this is the best solution but it appears to work.
Let me know if you have further advice.
