I have created a Custom Post Type in WordPress called “Found”. Inside that, I have created two taxonomies, “Pets” (named petsfound) and “Electronics” (named electronicsfound) and both of those taxonomies have various terms.

If I view the posts that use the taxonomy terms on the site, they show correctly, however, attempting to view a list of posts for the taxonomy shows a 404. So, the following happens:

https://example.com/found/pets-found/ shows a 404 page.

https://example.com/found/pets-found/dog shows the list of dogs in the pets found taxonomy.

I have tested with using both archive.php and taxonomy-petsfound.php but both show the 404 for the taxonomy. This is the same for the electronics taxonomy too.

Below is the code for the “Found” CPT and “petsfound” Taxonomy:

function found_custom_post_type() {
    $labels = array(
        'name'                  => _x( 'Found Items', 'Post Type General Name', 'lost_and_found' ),
        'singular_name'         => _x( 'Found', 'Post Type Singular Name', 'lost_and_found' ),

    );
    register_taxonomy( 'petsfound', 'found', $args );
    flush_rewrite_rules();
}
add_action( 'init', 'found_taxonomies_pets', 1 );
  • I have reset the permalinks on multiple occasions.
  • I have tested amending the hierarchical and with_front values from true to false and back again in case they had any affect.
  • I have ran print_r($wp_query); on the 404.php template and receive the following for the start of the query_vars:

    [query_vars] => Array ( [page] => 0 [found] => pets-found [post_type] => found [name] => pets-found

Not sure what else to look to, so hopefully someone can help.

Cheers

Damien
