我正在创建一个Wordpress自定义帖子类型，包括一个分类法，在安装之后，所有的永久链接都被刷新了，但是分类法归档页面不断给我404。

CPT归档页面工作得非常好。

要创建的代码：

add_action( \'init\', \'register_cpt_post_type\' );
function register_cpt_post_type() {
    register_post_type( \'offers\',
        array(
            \'labels\' => array(
                \'name\' => \'Offer Posts\',
                \'menu_name\' => \'Offers Manager\',
                \'singular_name\' => \'Offer post\',
                \'all_items\' => \'All Offers Posts\'
            ),
            \'public\' => true,
            \'publicly_queryable\' => true,
            \'show_ui\' => true,
            \'show_in_menu\' => true,
            \'show_in_nav_menus\' => true,
            \'supports\' => array( \'title\', \'editor\', \'author\', \'thumbnail\', \'comments\', \'post-formats\', \'revisions\' ),
            \'hierarchical\' => false,
            \'has_archive\' => \'offers\',
            \'show_in_rest\' => true,
            \'taxonomies\' => array(\'offers-category\')
        )
    );
    register_taxonomy( \'offers-category\', array( \'offers\' ),
        array(
            \'labels\' => array(
                \'name\' => \'Offer Categories\',
                \'menu_name\' => \'Offer Categories\',
                \'singular_name\' => \'Offers Category\',
                \'all_items\' => \'All Categories\'
            ),
            \'public\' => true,
            \'hierarchical\' => true,
            \'show_ui\' => true,
            \'show_in_rest\' => true,
            \'rewrite\'=>array( \'slug\'=>\'offers\' )
        )
    );
}

如果我尝试访问www.xxx。com/offers->它工作得非常好，并为我提供了存档页面模板

如果我尝试访问www.xxx。com/offers/food->如果食品是一个类别，页面将指向404。

如果我设置了一些错误，你能指导我吗？
