title: Drupal: drupal_set_message doesnt display a message
body: <p>I cannot seem to get a message from drupal_set_message when a user registers on my site.
  I'm using Drupal 6.14.</p>
  
  <p>Adding a print in the user.module:</p>
  
  <pre><code>function user_register_submit($form, &amp;$form_state) {
    ...
        if ($notify) {
          ...
        }
        else {
          drupal_set_message(t('Your password and further instructions have been sent to your e-mail address.'));
          print 'xxxxxx';
          $form_state['redirect'] = '';
          return;
        }
      }
      ...
  
  }
  </code></pre>
  
  <p>It prints 'xxxxx';</p>
  
  <p>A <code>var_dump</code> of the <code>$_SESSION</code> variable gives the status message, which <code>drupal_set_message</code> doesnt display, so that looks fine also.</p>
  
  <p>I've uninstalled all my modules, only core remains, and using Garland now as a theme.</p>
  
  <p>Furthermore, I've installed a fresh Drupal installation, and there it gives me a nice status message.</p>
  
  <p>Then i compared my .htaccess and Drupal's, from the fresh install. Modified mine to make them equal.</p>
  
  <p>Nothing helps.</p>
  
  <p>Any thoughts?</p>
