title: .htaccess ErrorDocument 404 not showing up
body: <p>I have a server from AWS EC2 service running on Linux ubuntu and I have installed apache, php, and mysql.</p>
  <p>I have added a <code>.htaccess</code> file in my document root <code>/var/www/html</code>.</p>
  <p>I entered this code in it:
  <code>ErrorDocument 404 /var/www/html/404.php</code> and it is still not showing up.</p>
  <p>I kept entered this command multiple times: <code>sudo service httpd restart</code> to restart the server but no changes displayed...</p>
  <p>How can I fix this... Did I do something wrong?</p>
