Posts not being hidden

Thank you for reporting this.

Unfortunately the plugin does currently not support hiding posts from archives, lists or widgets. This is a highly requested feature, but there is no ETA on when it will be implemented.

I do have a snippet you can insert in your theme’s functions.php that will hide restricted posts from any list. However, it only works for posts selected directly as conditions, not for posts in categories.

add_action( 'pre_get_posts', function($query) {
	if (!is_admin() && !$query->is_singular() && (!isset($query->query["post_type"]) || $query->query["post_type"] != RUA_App::TYPE_RESTRICT)) {
		global $wpdb;
		$other_levels = array_diff(
			array_keys(RUA_App::instance()->get_levels()),
			RUA_App::instance()->level_manager->get_user_levels()
		);
		$result = $wpdb->get_col("SELECT m.meta_value FROM $wpdb->postmeta m INNER JOIN $wpdb->posts p ON m.post_id = p.ID WHERE m.meta_key = '_ca_post_type' AND p.post_parent IN ('".implode("','", $other_levels)."')");
		if($result) {
			$query->set('post__not_in', $result);
		}
	}
	return $query;
} );
