自定义post类型单页显示404错误

我正在使用” Toro_Unit自定义post类型永久链接”插件来自定义网址。

这是我的自定义post类型

<?php

/**
 * Post Type: our-products.

    $labels = array(
        "name" => __("Our Products", "twentynineteen"), "singular_name" => __("Product", "twentynineteen"), "menu_name" => __("Products", "twentynineteen"), "all_items" => __("Products", "twentynineteen"), "add_new" => __("Add Products", "twentynineteen"), "add_new_item" => __("Add New Product", "twentynineteen"), "edit_item" => __("Edit Product", "twentynineteen"), "new_item" => __("New Product", "twentynineteen"), "view_item" => __("View Product", "twentynineteen"), "view_items" => __("View Products", "twentynineteen"), "search_items" => __("Search Products", "twentynineteen"), "not_found" => __("No Product Found", "twentynineteen"), "not_found_in_trash" => __("No Product Found in Trash", "twentynineteen"), "parent_item_colon" => __("Parent Product", "twentynineteen"), "featured_image" => __("Featured Image", "twentynineteen"), "set_featured_image" => __("Set Featured Image for Product", "twentynineteen"), "remove_featured_image" => __("Remove Featured Image for Product", "twentynineteen"), "use_featured_image" => __("Use as Featured Image For Product", "twentynineteen"), "archives" => __("Product Archieves", "twentynineteen"), "insert_into_item" => __("Insert into Products", "twentynineteen"), "uploaded_to_this_item" => __("Upload to this product", "twentynineteen"), "filter_items_list" => __("Filter Product List", "twentynineteen"), "items_list_navigation" => __("Filter Product List Navigation", "twentynineteen"), "items_list" => __("Products List", "twentynineteen"), "attributes" => __("Product Attributes", "twentynineteen"), "name_admin_bar" => __("Products", "twentynineteen"), "parent_item_colon" => __("Parent Product", "twentynineteen"), );

flush_rewrite_rules( false );

我想制作自定义分类的网址

site_url /我们的产品/自定义分类名称

和单页

site_url /我们的产品/自定义分类名称/单页网址

所以在设置时

网址正常。但显示404错误。

• 通过设置刷新永久链接->永久链接->自定义结构->保存
• 在functions.php中以及创建自定义post类型时flush_rewrite_rules(false)
• 这里提供的解决方案
• 还尝试了这个解决方案
• .htaccess文件：没问题。
• 经过无奈之后, 安装了新的设置, 创建了自定义post类型, 并将永久链接设置为/％category％/％postname％/, 不适用于自定义post类型。

仅供参考, 我使用的是wordpress 5.3.1, 并且与主题或插件没有冲突。经过测试。

注册自定义post类型时, 请将其添加到自定义post类型中

"taxonomies" => [ "category", "product-category" ], 

当时有效
