</html> PROBLEMA: se pierden los datos de $_SESSION.
En login.php si el user existe ($user->Exist()) cargo en $_SESSION el name y el id y me redirige a index.php
El problema es que cuando en index.php verifica si esta seteado $_SESSION['username'] el array $_SESSION esta en 0, sin valor (eso que tendria que estar cargado por el login). Y como la condicion es falsa vuelvo a login.php y asi infinitamente.
Esto me pasa solamente como uso PDO en Exist() si uso mysqli funciona bien!
No se que es lo que estoy haciendo mal.
