# Function removes main menu

 * I’m using the following function in _function.php_ to display a custom post type
   in the main loop on a custom taxonomy page.
 *     ```
       function namespace_add_custom_types( $query ) {
         if( is_tax() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {
           $query->set( 'post_type', 'route' );
       	  return $query;
       	}
       }
       add_filter( 'pre_get_posts', 'namespace_add_custom_types' );
       ```
   
 * However when the taxonomy page is displayed the main menu doesn’t load. If I 
   comment out the function the menu loads so I’m pretty sure the template is OK.
 * Any ideas?

 * the ‘menu’ is also a post type;
    [http://codex.wordpress.org/Post_Types](http://codex.wordpress.org/Post_Types)
 * try to check for the main query (untested):
 *     ```
       if( ( is_tax() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) && ! $query->is_main_query() ) {
       ```

 * Thanks for the suggestion. Turns out it was a WP3.0 fix in the theme template
   that was screwing things up.
