title: Drupal7. url from hook menu (and other) not work
body: <p>Hi I have a old installation of Drupal 7 with some different subdomain</p>
  <p>in the implement of hook menu we have some items like this</p>
  <pre><code>    $items['my-url'] = array(
      'page callback' =&gt; '\XXX\Controllers\MyurlController::indexAction',
      'access arguments' =&gt; array('access content'),
      'type' =&gt; MENU_CALLBACK,
  );
  </code></pre>
  <p>When I call it from the main domain, no problem. But when I call it from a subdomain, I have a 404.
  mydomain.fr/fr/my-url is working
  subdomain.mydomain.fr/fr/my-url doesn't work.</p>
  <p>Same thing for /admin or /login. It works on domain but not in subdomain.</p>
  <p>Would anyone know why and how to correct?
  Thanks</p>
