title: php variable not found with vtiger code
body: <p>I am installing vtiger in my mac os.</p>
  
  <p>i am getting this error when accessing <code>index.php</code></p>
  
  <pre><code>Notice: Undefined variable: mod_strings in /Applications/XAMPP/xamppfiles/htdocs/vtigercrm/modules/CustomView/CustomView.php on line 17
  </code></pre>
  
  <p>So the error clearly says that there is a variable <code>mod_strings</code> that is not identified.</p>
  
  <p>I went to <code>index.php</code> and I found this:</p>
  
  <pre><code>include_once 'include/Webservices/Relation.php';
  include_once 'vtlib/Vtiger/Module.php';
  include_once 'includes/main/WebUI.php';
  
  $webUI = new Vtiger_WebUI();
  $webUI-&gt;process(new Vtiger_Request($_REQUEST, $_REQUEST));
  </code></pre>
  
  <p>As you see, the error tells me that the variable is in the <code>CustomView.php</code>. So I opened that file, and I found the followings:</p>
  
  <pre><code>require_once('data/CRMEntity.php');
  require_once('include/utils/utils.php');
  require_once 'include/Webservices/Utils.php';
  </code></pre>
  
  <p>as you see, the code is using a php script called <code>CRMEntity</code>, i opened that file and I found this:</p>
  
  <pre><code>global $adb, $mod_strings;
  </code></pre>
  
  <p>so look the variable <strong>IS</strong> there. why i am getting that error?</p>
