custom taxonomy archive permalink shows 404 error

In my plugin I have a custom post type with a slug of ‘ready-to-wear’ and I have a custom taxonomy called ‘seasons’ associated with it.

The odd thing is that this url with query works:

http://dev.catwalkyourself.com/ready-to-wear/?seasons=autumn-winter-2012-2013-en

but the same one with custom permalink doesn’t:

http://dev.catwalkyourself.com/ready-to-wear/seasons/autumn-winter-2012-2013-en

It throws a 404 error. You can try pasting the links yourself.

Here is my relevant plugin code:

Here is where the custom post type is registered

$post_types = array();

    $post_types['rtw'] =  $args = array(
        'labels' => array(
            'name' => __('RTW Collections'),
            'singular_name' => __('Ready to Wear Collection'),
            'add_new' => __('Add new RTW collection'),
            'add_new_item' => __('Add a new show to the RTW collection'),
            'edit_item' => __('Edit Collection'),
            'view_item' => __('View Collection'),
            'search_items' => __('Search Ready to Wear Collections'),
            'not_found' => __('No RTW Collections found'),
            'not_found_in_trash' => __('No RTW Collections found in trash')
        ),
        'query_var' => 'rtw_collections',
        'supports' => array('title', 'editor', 'thumbnail', 'author', 'comments'),
        'has_archive' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'taxonomies' => array('seasons','city'),
        'rewrite' => array(
            'slug' => 'ready-to-wear',
            'with_front' => false
        ),
        'public' => true,
        'menu_position' => 6
    );

Here is where the taxonomy is configured:

$taxonomies = array();

    $taxonomies['seasons'] = array(
        'query_var' => 'seasons',
        'rewrite' => array(
            'slug' => 'seasons',
            'with_front' => false
        ),
        'single_value' => true,
        'required' => true,
        'labels' => array(
            'name' => __('Seasons'),
            'singular_name' => __('Season'),
            'edit_item' => __('Edit Season'),
            'update_item' => __('Update Season'),
            'add_or_remove_items' => __('Add or remove seasons'),
            'new_item_name' => __('Add new Season'),
            'all_items' => __('All Seasons'),
            'search_items' => __('Search Seasons'),
            'popular_items' => __('Popular Seasons'),
            'separate_items_with_commas' => __('Separate Items with commas'),
            'choose_from_most_used' => __('Choose from most used Seasons')
        )
    );

and here is the call to register_taxonomy:

foreach ($taxonomies as $taxonomy => $arr) {
            register_taxonomy($taxonomy, null, $arr);
        }

I have tried:

  • Flushing the permalinks repeatedly
  • Setting ‘with_front’ true and false repeatedly
  • add flush_rewrite action to my functions.php

Unfortunately, none of these work. Please help me out.
