title: PHP include not working from other directory
body: <p>I have a small PHP application that works fine on many hosting accounts and on my local server.</p>
  
  <p>I'm trying to set it up for a client but the includes don't seem to work. If I am inside the application directory, all includes work fine but if I try include a file from inside this  directory into a file that is located outside of this directory, it is not included. I get no errors. The php file is just not included.</p>
  
  <p>I have the very same setup on other accounts and everything works fine. I am thinking that it may be some security permission settings or php.ini configuration issue.</p>
  
  <p>Since I don't get any error, I don't know where to start looking. The include look like this:</p>
  
  <pre><code>&lt;?php require_once('foldername/foldername/filename.php');?&gt;
  </code></pre>
  
  <p>How can I start investigating where the problem is?</p>
  
  <p>Thank you very much.</p>
