Hi,
Check your config.php (Osclass root folder):
define('REL_WEB_URL', '/');
define('WEB_PATH', 'http://your.domain.com/');
This if yourdomain.com points directly to Osclass root folder. In the case of rohit_bhardwaj it would need to be:
define('REL_WEB_URL', '/old_books/');
define('WEB_PATH', 'http://aawake.com/old_books/');
Regards
