创建不受WordPress影响的子文件夹

我在根目录中安装了一个WordPress站点 . 我在子文件夹/商店中为此站点添加了一个在线商店 . 在/ shop文件夹中是一个index.php文件和这个.htaccess文件：

#/shop/.htaccess
RewriteEngine on
RewriteRule ^([^/\.]+)/?$ index.php?arg1=$1 [L,QSA]
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?arg1=$1&arg2=$2 [L]

一些示例有效的URL是：

http://www.mysite.com/shop/
http://www.mysite.com/shop/clothes
http://www.mysite.com/shop/shoes
http://www.mysite.com/shop/hats

这些网址显示正常， but the header is a 404 会导致Google出现问题 .

这是请求标头：

这是响应头：

在我的/shop/index.php文件中，我尝试手动输出状态为200的 Headers ，但它没有解决问题 .

我尝试将以下内容添加到根.htaccess文件（WordPress的）但它没有工作：

ErrorDocument 401 default

在根.htaccess文件（WordPress的）中，我尝试在WordPress的RewriteRules之前，之后和之内添加这些命令，但我仍然得到404标头：

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/shop/(.*)$
RewriteRule ^.*$ - [L]

/ shop文件夹和子文件夹具有0755权限，文件具有0644，所有文件与WordPress安装具有相同的所有者/组 .

任何帮助表示赞赏 . 谢谢 .
