[wp-hackers] Listing taxonomies archive return 404 (again?)

[Diana K. Cury]

I had this solved in previous WP version:

When listing a taxonomy archive (i.e. taxonomy is 'flavors' and trying to access http://site.com/flavors), in previous version I only had to visit Permalinks page to re-write the permalinks for this new taxonomy.

Now, it seems doesn't work anymore.

I have a taxonomy 'genres' for 'art post type, 'this way:

  register_taxonomy('genres','art', array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'query_var' => true,
    'rewrite' => array( 'slug' => 'genres', 'with_front' => FALSE ),
  ));

Whenever a try to access the /genres, I get a 404. 

Is this issue back again?! Something to do with permalinks structure in use? I do have to create a taxonomy-{taxonomy}.php for every taxonomy?

Thanks
