几天前，我改变了我的网站上的永久链接从这种格式：/index.php/year/month/postName到/postName，我注意到我从保留旧结构的外部链接中得到了很多404错误。
如何使用.htaccess将点击/index.php/year/month/postName的用户重定向到/postName？因此，不要错过这些访问。
我已经尝试了这个代码，但仍然存在错误：

RedirectMatch 301 ^/index\.php/([0-9]+)/([0-9]+)/(.*)$ https://www.example.com/$3

$4也是如此。
下面是我的htaccess代码：

RewriteEngine On
AcceptPathInfo On
RewriteRule ^index\.php/\d{4}/\d\d/([^/]*) https://www.example.com/$1 [R=301,L]

<IfModule mod_rewrite.c>
