[quote author="Bart v B" date="1271673952"]?? don't know what voodo there must be.. Only md5()

Code:

$user_profile = array(
'username'=> $this->input->post('reg_username'),
'password' => md5($this->input->post('reg_password')),
'email' => $this->input->post('email')
);

And it's done.. [/quote]

thanks! it really is about the md5. I fail to notice the md5 set at the configuration of my Form Validation Class.
