$this->session->set_flashdata not working in codeigniter?why? what is the solution for this.

while using set_flashdata() function, if it will throw below error as follows “In order to use the Session class you are required to set an encryption key in your config file” In this condition we have to set $config[‘encryption_key’] =” in the config.php file flash data will work fine if you set the encryption_key.
