/includes/modules/order_total/ot_payment.php

[2021-08-02 16:23:53]	[warning]	[modified]	[pid:7493]	Backtrace #3 - /PATH/shopping_cart.php called at Line 55	{}	{}

Fix:
Ersetzen von $_SESSION['billing_zone'] durch $order->billing['country']['iso_code_2'], da erstes nicht definiert an der Stelle.
Nicht sicher. evtl. resultiert das Warning aus den Änderungen zu ​Ticket #1971 ? (nicht geprüft)

Fix:
In beiden Funktionen wo die Variable vorkommt diese vor den jeweiligen if-Clauses definieren und nicht innerhalb, also nach den global-Definitionen.
