title: Zend Failed opening Zend/Application.php
body: <p>Ok, so I am relatively new to Zend. I have created a new application and started to build an authentication system based on <a href="http://akrabat.com/zend-auth-tutorial/" rel="nofollow noreferrer">a guide</a>. However, the server is kicking out an Internal Server Error.</p>
  <p>Upon checking the PHP error logs I have been given the following two errors:</p>
  <blockquote>
  <p>[Thu Jul 19 10:26:40 2012] [error] [client 80.194.255.4] PHP Warning:  require_once(Zend/Application.php): failed to open stream: No such file or directory in /home/www-data/zend.danielgroves.net/htdocs/public/index.php on line 18</p>
  <p>[Thu Jul 19 10:26:40 2012] [error] [client 80.194.255.4] PHP Fatal error:  require_once(): Failed opening required 'Zend/Application.php' (include_path='/home/www-data/zend.danielgroves.net/htdocs/library:.:/usr/share/php:/usr/share/pear') in /home/www-data/zend.danielgroves.net/htdocs/public/index.php on line 18</p>
  </blockquote>
  <p>The controller:-</p>
  <pre><code>class Admin_AuthController extends Zend_Controller_Action 
  { 
      public function init() 
      { 
           /* Initialize action controller here */ 
      } 
  
      public function indexAction() 
      { 
          $form = new Application_Form_login(); 
          $request = $this-&gt;getRequest(); 
          if ($request-&gt;isPost()) { 
              if ($form-&gt;isValid($request-&gt;getPost())) {
             
              } 
          }
          $this-&gt;view-&gt;form = $form;
      }
  }
  </code></pre>
  <p>Any ideas on what the cause of this could be?  As I said I am new to Zend so I don't really know where to start when it comes to these errors, especially as this is referencing files that were created by the Zend CLI tool.</p>
  <p>Any pointers/suggestions etc would be muchly appriciated.</p>
