title: Call to undefined function base_url()
body: <p>I get this error when I try to load base_url funcion. The problem is that I've already added base_url to autoload file but the issue still:</p>
  
  <pre><code>$autoload['helper'] = array('url');
  </code></pre>
  
  <p>views/home.php file has the following code:</p>
  
  <pre><code>    &lt;!doctype html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;meta name="viewport"
            content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"&gt;
      &lt;meta http-equiv="X-UA-Compatible" content="ie=edge"&gt;
      &lt;title&gt;Document&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div align="center"&gt;
      &lt;h1&gt;Index&lt;/h1&gt;
      &lt;a href="&lt;?= base_url()?&gt;"&gt;Link&lt;/a&gt;
  &lt;/div&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Any ideas? Since base_url function is being loaded by autoload I don't know what else should I try to do to fix this.</p>
  
  <p>Thank you!</p>
