title: Custom 404 php page returning 200 instead of 404
body: <p>I have set up a custom 404 page and have the following code within the header:</p>
  
  <pre><code>&lt;?php
  header("HTTP/1.0 404 Not Found");
  ?&gt;
  </code></pre>
  
  <p>Then within my .htaccess file I have the following:</p>
  
  <pre><code>ErrorDocument 404 /404.php
  </code></pre>
  
  <p>However for some reason when testing the site I am told the page is still returning a 200 instead 404 error. Any suggestions?</p>
