Fatal error

[DAXESH]

Hi I am using itop version 3.1. While I run the setup wizard, I get the following error:
Fatal error: Uncaught Error: Call to undefined method AjaxPage::error() in /var/www/html/itop_viswas/web/setup/ajax.dataloader.php:169
Stack trace:

thrown in /var/www/html/itop_viswas/web/setup/ajax.dataloader.php on line 169
PHP error occured : msg=Uncaught Error: Call to undefined method AjaxPage::error() in /var/www/html/itop_viswas/web/setup/ajax.dataloader.php:169
Stack trace:

thrown, no=1, file=/var/www/html/itop_viswas/web/setup/ajax.dataloader.php, line=169

Please guide me why I am getting error.
