title: Lynda.com - Building an online portfolio on wordpress
body: <p>It works on the video, as they told, I created a file called posttypes.php into the theme folder containing this code:</p>
  
  <pre><code>&lt;?php
  echo "Hello!";
  ?&gt;
  </code></pre>
  
  <p>I have made a file called functions.php put into the child theme cooking:</p>
  
  <pre><code>&lt;?php
  include_once(ABSPATH . 'wp_content/themes/posttypes.php');
  ?&gt;
  </code></pre>
  
  <p>As a consequence, I should have visually outputten a Hello! This is not the case, I have the following error output:</p>
  
  <blockquote>
    <p>Warning:
    include_once(C:\wamp\www\portfolio/wp_content/themes/posttypes.php)
    [function.include-once]: failed to
    open stream: No such file or directory in
    C:\wamp\www\portfolio\wp-content\themes\cooking\functions.php on line
    2'</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
