Ich hab ein Usersystem, mit Register,Login,logout und config (aus Google). Aber bei mir kommt ein Fehler, wenn ich auf register.php oder login.php gehe. Es gibt mir eine Fehlermeldung :
In dieser Linie ist aber dashier :
Keine Ahnung was falsch ist, versuche es schon seit 1 Stunde..
Hier mal die ganzen Codes :
config.php
Das mit Datenbank User usw. hab ich schon verändert,die sind auch 100% richtig.
login.php
logout.php
register.php
Wo liegt das Problem ?
