404 not found page not working with my .htaccess

Question

I have below .htaccess on the server with the not found page rules but it doesn\'t seems to work. Any idea?

RewriteEngine on
RewriteRule ^article_detail/([a-zA-Z         


        

Answer 1

Have you tried ErrorDocument 404 /main/404_not_found.html?

Just incase you have something interfering with your URL (not sure if that is your complete htaccess)? I usually don't put the whole URL in although technically you can.

Also can you access the 404 page directly?
