我对嵌套permalink有问题。我的URL结构如下：

Catalog -> Category -> Product

我的URL是：

• www.domain.com/catalogs （用于存档目录）www.domain.com/catalogs/%catalog% （对于包含类别列表的单个目录页）www.domain.com/catalogs/%catalog%/%category% （对于包含产品列表的单一类别页面）www.domain.com/catalogs/%catalog%/%category%/%product% （对于单个产品页）

在WP Backoffice和Frontoffice中，所有url都是正确的，我唯一的问题是在访问产品页时，例如：

www.domain.com/catalogs/catalog-001/category-001/product-001

在那里，我收到了404错误。我的代码如下：

这是我的。htaccess：

这里是“重写分析器”插件中的图像：
