.htaccess 404无法使用RewriteRule

Question

我正在尝试设置干净的URL和从同一index.php页面提供的自定义404页面。干净的网址正在运行，但404不是，我在哪里错了？

ErrorDocument 404 /index.php?p=404

AddType application/x-httpd-php .rss

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^([a-zA-Z0-9-\w]+)$ index.php?p=$1
RewriteRule ^([a-zA-Z0-9-\w]+)/$ index.php?p=$1
