title: Wordpress - That page can’t be found
body: <p>I have installed and configured on apache server wordpress (I didn't do that, I am not expert on websites). Now I uploaded my php application so root structure looks like this:</p>
  
  <p>...
  images
  voucher (this is my application)
  wp-admin
  wp-content
  wp-includes</p>
  
  <p>When I input <a href="http://address.com/voucher/index.php" rel="nofollow">http://address.com/voucher/index.php</a> into browser I got Wordpress error which contains information "Oops! That page can’t be found.". I don't know why is it trying to achieve my voucher catalog "by Wordpress system", maybe should I set some settings (.htacces or smth like this)?</p>
