Custom taxonomy results in 404 error

Hi

I registered a custom taxonomy which worked well in my previous theme.
After changing the theme to Enfold, custom taxonomy archive page results in 404 error.

I declared the taxonomy as follows in the functions.php file:

function add_custom_taxonomies() {
  // Add new "Area" taxonomy to Posts
  register_taxonomy('speciality', 'post', array(
    // Hierarchical taxonomy (like categories)
    'hierarchical' => true,
    // This array of options controls the labels displayed in the WordPress Admin UI
    'labels' => array(
      'name' => _x( 'Specialities', 'taxonomy general name' ),
      'singular_name' => _x( 'Speciality', 'taxonomy singular name' ),
      'search_items' =>  __( 'Search Specialities' ),
      'all_items' => __( 'All Specialities' ),
      'parent_item' => __( 'Parent Speciality' ),
      'parent_item_colon' => __( 'Parent Speciality:' ),
      'edit_item' => __( 'Edit Speciality' ),
      'update_item' => __( 'Update Speciality' ),
      'add_new_item' => __( 'Add New Speciality' ),
      'new_item_name' => __( 'New Speciality Name' ),
      'menu_name' => __( 'Specialities' ),
    ),
    // Control the slugs used for this taxonomy
    'rewrite' => array(
      'slug' => 'specificarea', // This controls the base slug that will display before each term
      'with_front' => false, // Don't display the category base before "/locations/"
      'hierarchical' => true // This will allow URL's like "/locations/boston/cambridge/"
    ),
  ));
}
add_action( 'init', 'add_custom_taxonomies', 0 );

Is there a way to correct this issue?
(One more question: Using custom taxonomy will affect the loading speed of the site? If then, I will just remove them.)
