title: Problem deploying Zend Framework website: doesn't find the classes
body: <p>I'm trying to deploy a website made with the Zend Framework. The website is running fine on my local environment, I'm trying to deploy it on my VPS. But I'm running into some difficulties.</p>
  
  <p>Now it says the following:</p>
  
  <p>*Fatal error: Class 'Doctrine_Manager' not found in /is/htdocs/wpxxxxx/www/mensenenjij/application/Bootstrap.php on line 12*</p>
  
  <p>It properly includes the Doctrine classes but it can't instantiate a new Doctrine_Manager. Anybody knows why?</p>
  
  <p>Bootstrap.php:</p>
  
  <pre><code>&lt;?php
  
  class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
  {
      protected function _initDoctrine()
      {
          require_once 'Doctrine/Doctrine.php';
          $this-&gt;getApplication()
               -&gt;getAutoloader()
               -&gt;pushAutoloader(array('Doctrine', 'autoload'), 'Doctrine');
  
          $manager = Doctrine_Manager::getInstance();
          $manager-&gt;setAttribute(
              Doctrine::ATTR_MODEL_LOADING,
              Doctrine::MODEL_LOADING_CONSERVATIVE
          );
  
          $config = $this-&gt;getOption('doctrine');
          $conn = Doctrine_Manager::connection($config['dsn'], 'doctrine');
          return $conn;
      } 
  }
  </code></pre>
