Problems with autentification

[teoj]

When the password is wrong show the message Incorrect Login but when it is correct go to auth/login again without any messages. I have working on it 2 days.
I clone in ThirtParty/CodeIgniter-Ion-Auth with git like in the documentation INSTALL.MD.
In Config/Autoload.php i put :
public $psr4 = [
APP_NAMESPACE => APPPATH, // For custom app namespace
'Config' => APPPATH . 'Config',
'IonAuth' => APPPATH . 'ThirdParty/CodeIgniter-Ion-Auth'
];
In Config/IonAuth.php :

Ok i find the solution.
The problem was the filter.
