it seems, that the plugin does not save the soap password.
I was assigned a new one and alway get errors on checkout like:
Fatal error: Call to undefined method ListPaymentMethodsResponse::getExternalStatus() in xxx/wp-content/plugins/woocommerce-mpay24-gateway/class-wc-mpay24-shop.php on line 342
When I change the description text it does also not remember the cahnges it stays like "Mit Kreditkarte bezahlen"
Is there a way to check somewhere in the database if the soap pw is changed uppon saving?
