Hallo ich habe ein Loginskript, dass die Information des Users ($one) anhängen soll, jedoch wird ein Link erstellt bei der die Variable leer zu sein scheint. Ich habe mir das Skript mehrmals angeschaut aber kein Fehler gefunden. Aber mehrere Augen sehen ja bekanntlich mehr als zwei: Vielleicht findet hier ja jemand einen Fehler (Das einloggen funktioniert ja):
