title: CodeIgniter CI_Controller not found
body: <p>So basically, the below is the code I have right now:</p>
  
  <pre><code>class MY_Log extends CI_Log {
  
      /**
      * Variable storing the CodeIgniter instance.
      *
      * @access private
      * @since v0.1.0.0
      */
      private $CI;
  
      /**
      * Constructor for later use by internal
      * methods.
      *
      * @access public
      * @since v0.1.0.0
      */
      public function __construct()
      {
          // Extend the parent logging.
          parent::__construct();
  
          $this-&gt;$CI =&amp; get_instance();
      }
  }
  </code></pre>
  
  <p>And I get the following error;</p>
  
  <pre><code>Fatal error: Class 'CI_Controller' not found in /&lt;deleted&gt;/system/core/CodeIgniter.php on line 233
  </code></pre>
  
  <p>This is kinda how the user guide describes it.</p>
