Was könnte das Problem dazu sein?

Ok, für alle die vielleicht mal das gleiche Problem bekommen, hier die Lösung: Das aktuelle PayPal Plugin (Ver. 3.0.1) wird im Backend-Menü über Kunden -> Zahlungen - PayPal -> Einstellungen konfiguriert. Das funktioniert natürlich problemlos. Bei mir ist jedoch immernoch die alte Konfiguration über Einstellungenen -> Grundeinstellungen -> PayPal vorhanden. Und darüber habe ich versucht die Konfiguration zu speichern, welche natürlich mit einer Fehlermeldung endete. Für mich stellt sich jetzt noch die Frage, warum die alte Konfiguration noch vorhanden ist? Wie kann ich diesen Menüeintrag sicher entfernen?

Hi. Habe ähnliches Problem. Hat hier jemand eine Lösung?
