title: VK API: Incorrect signature: sid & secret authorization
body: <p>I'm trying to start up with a vk.com tab app and I'm using the php api sdk and for some reason when I try to get the user profile info I get this:</p>
  
  <pre><code>Incorrect signature: sid &amp; secret authorization
  </code></pre>
  
  <p>the code is as fallows:</p>
  
  <pre><code>try {
  
  $vkontakte = new VKontakte(array('testMode'   =&gt; true, 'fileUpload' =&gt; false));
  $vkontakte-&gt;setApiId(XXXXXXX);
  $vkontakte-&gt;setSecret('XXXXXXXXXX');
  
  $viewerId = $vkontakte-&gt;getViewerId();
  
  $profiles = $vkontakte-&gt;getProfiles(array(
      'uids'   =&gt; $viewerId,
      'fields' =&gt; 'nickname,sex,bdate,photo,photo_big,mobile_phone,has_mobile,home_phone,rate'
  ));
  } catch (Exception $e) {
  echo '&lt;pre&gt;';
  echo $e-&gt;getMessage();
  echo '&lt;/pre&gt;';
  }
  </code></pre>
  
  <p>Any idea what might be wrong here? or what should be done?</p>
