为什么自定义帖子类型存档和单页显示 404 错误

如何解决为什么自定义帖子类型存档和单页显示 404 错误

我创建了一个名为 Portfolio 的自定义帖子类型。创建帖子类型后，我更新了永久链接。但是当我转到自定义帖子类型存档页面或单个页面时，它会显示 404 错误。

这是存档页面： https://dc1.justcreative.com/portfolio-item/
这是单页： https://dc1.justcreative.com/portfolio-item/primitive/

这是自定义帖子类型代码：

function jc_portfolio_post_type() {
    $labels = array(
        'name'                  => _x( 'Portfolio','Post Type General Name','jc' ),'singular_name'         => _x( 'Portfolio','Post Type Singular Name','menu_name'             => __( 'Portfolio','name_admin_bar'        => __( 'Portfolio','archives'              => __( 'Item Archives','attributes'            => __( 'Item Attributes','parent_item_colon'     => __( 'Parent Item:','all_items'             => __( 'All Items','add_new_item'          => __( 'Add New Item','add_new'               => __( 'Add New','new_item'              => __( 'New Item','edit_item'             => __( 'Edit Item','update_item'           => __( 'Update Item','view_item'             => __( 'View Item','view_items'            => __( 'View Items','search_items'          => __( 'Search Item','not_found'             => __( 'Not found','not_found_in_trash'    => __( 'Not found in Trash','featured_image'        => __( 'Featured Image','set_featured_image'    => __( 'Set featured image','remove_featured_image' => __( 'Remove featured image','use_featured_image'    => __( 'Use as featured image','insert_into_item'      => __( 'Insert into item','uploaded_to_this_item' => __( 'Uploaded to this item','items_list'            => __( 'Items list','items_list_navigation' => __( 'Items list navigation','filter_items_list'     => __( 'Filter items list',);
    $rewrite = array(
        'slug'                  => 'portfolio-item','with_front'            => true,'pages'                 => true,'Feeds'                 => true,);
    $args = array(
        'label'                 => __( 'Portfolio','description'           => __( 'Post Type Description','labels'                => $labels,'supports'              => array( 'title','editor','thumbnail','revisions' ),'taxonomies'            => array( 'portfolio_filter' ),'hierarchical'          => false,'public'                => true,'show_ui'               => true,'show_in_menu'          => true,'menu_position'         => 5,'show_in_admin_bar'     => true,'show_in_nav_menus'     => true,'can_export'            => true,'has_archive'           => true,'exclude_from_search'   => false,'publicly_queryable'    => true,'rewrite'               => $rewrite,'capability_type'       => 'page',);
    register_post_type( 'portfolio',$args );
}
add_action( 'init','jc_portfolio_post_type',0 );

有人告诉我如何解决这个问题？
