I have build my own component. I know very well about these stuff but all of sudden I wonder that the joomla request to my custom component is not displaying anything. Its displaying blank page. See this: http://designsoft.bestplacestestserver.com/index.php?option=com_marketplacemanager
Here is the very initial code of 'marketplacemanager.php' file of component where the request is not arriving. Don't know why.
Code - marketplacemanager.php
defined('_JEXEC') or die;
jimport('joomla.application.component.helper');
echo 'aa'; exit; // should have something displayed as here
