Qcodo Manual problem - Login Form

Hi,
I'm a new qcodo user from italy!

I have a problem with “creating a login form” paragraph of the qcodo manual v05.pdf

error:  PHP Fatal error:  Call to undefined method User::loadbyusername()

$objUser = User::LoadByUsername($this->txtUsername->Text);

any ideas?

Thanks

Alessandro

Perfect!

ALTER TABLE  `user` ADD UNIQUE (
`username`
)

Thanks for your advice!

Alessandro
