i am trying to create a joomla template for my existing static website. I have also created an anatomy for the template. But, when i tried to open the website , keeping the template as default, it shows the following error:
'500 - Unable to load renderer class'

The code being used by me is:

defined('_JEXEC') or die('Restricted access');
