Child and grandchild taxonomy listings – 404

Solved by adding a filter and building the permalink. FIrt forget the pastebin code, just create a post type a nd the taxos you want, them add the filter:

add_filter('post_link', 'territorio_permalink', 10, 3);
add_filter('post_type_link', 'territorio_permalink', 10, 3);

function territorio_permalink($permalink, $post_id, $leavename) {
if (strpos($permalink, '%territorio%') === FALSE) return $permalink;

// Get post
$post = get_post($post_id);
if (!$post) return $permalink;

// Get taxonomy terms
$terms = wp_get_object_terms($post->ID, 'territorio');
if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0]))
$taxonomy_slug = $terms[0]->slug."https://wordpress.stackexchange.com/".$terms[1]->slug; //build here
else $taxonomy_slug = 'not-yet';

return str_replace('%territorio%', $taxonomy_slug, $permalink);
}

In post type creation use:

'rewrite' => array( 'slug' => 'anything-you-want/%territorio%','with_front' => false),

Note: if you want deeper links, your build should go deeper:

$taxonomy_slug = $terms[0]->slug."https://wordpress.stackexchange.com/".$terms[1]->slug."https://wordpress.stackexchange.com/".$terms[2]->slug;
