Custom taxonomies and slugs

Hi!

I’m trying to register a taxonomy using the following args:

$args = array(
‘labels’ => array(‘name’ => ‘Brands’, ‘singular_name’ => ‘Brand’),
‘public’ => true,
‘hierarchical’ => true,
‘show_ui’ => true,
‘show_in_nav_menus’ => true,
‘rewrite’ => array( ‘slug’ => ‘cameras/brands’, ‘with_front’ => false ),
‘query_var’ => true
);
register_taxonomy( ‘brand’, ‘camera’, $args );

But when I visit the following url I get a 404 Not Found error:

http://www.domain.com/cameras/brands/nikon

Any help in fixing the issue would be appreciated

Best,
