我在菜单中加入了一个类别。当我点击菜单中的类别时，这个类别没有显示任何内容。我预计至少会显示一篇自定义帖子类型的已发布帖子。

我的自定义帖子类型具有以下链接：

mysite.com/customPostTypeName/PostTitle

我的分类网站有以下链接：

mysite.com/category/testCategorie

我想在菜单中显示一个链接，该链接显示特定类别的所有帖子和自定义帖子类型。

有什么建议我做错了什么？

感谢您的回复！

UPDATE

我的帖子类型如下所示：

add_action( \'init\', \'cptui_register_my_cpts_matratze\' );
function cptui_register_my_cpts_matratze() {
    $labels = array(
        "name" => __( \'Matratzen\', \'\' ),
        "singular_name" => __( \'Matratze\', \'\' ),
        );

    $args = array(
        "label" => __( \'Matratzen\', \'\' ),
        "labels" => $labels,
        "description" => "",
        "public" => true,
        "publicly_queryable" => true,
        "show_ui" => true,
        "show_in_rest" => false,
        "rest_base" => "",
        "has_archive" => true,
        "show_in_menu" => true,
                "exclude_from_search" => false,
        "capability_type" => "post",
        "map_meta_cap" => true,
        "hierarchical" => false,
        "rewrite" => array( "slug" => "matratze", "with_front" => true ),
        "query_var" => true,

        "supports" => array( "title", "editor", "thumbnail", "excerpt", "trackbacks", "custom-fields", "comments", "revisions", "author", "page-attributes", "post-formats" ),      
        "taxonomies" => array( "category", "post_tag" ),
            );
    register_post_type( "matratze", $args );

// End of cptui_register_my_cpts_matratze()
}

我还没有注册任何分类法。

\'taxonomies\'  => array( \'category\' ),
