    Login Errati su PhpBB

    Voglio mettere nel mio forum che salva i login errati per vedere se dei lamer fanno dei tentativi di login... Quindi mi sono messo a modificareil login.php mettendo dopo il message_die(GENERAL_MESSAGE, $message); l'include alla pagina fatta da me che salva i log...

    come potete vedere da qui...

    login.php
    codice:
    <?php
