my favoritos.php

<?php
if(!is_user_logged_in()){
     $page = get_page_by_path( '/favoritos-2' );
     echo $page->post_content;
} else {
    global $favoritos, $query, $query_args;
    $query_args = array(
        'posts_per_page' => 32,
        'paged' => get_query_var( 'paged' ) ,
        'category' => -320,
        'post__in' => $favoritos
    );
    $query = new WP_Query($query_args);
    get_template_part('loop');
}
?>
