I'm using the IWD Onestepcheckout extension in combination with PAYONE (3.1.3). And I can't get PAYONEs payment method "Credit Card" to work.
The $configId in payone/core/helper/config.php is empty for this payment method. I think that this causes the error.
When I use Debit Payment or Online Bank Transfer everything works fine and the $configId isn't empty.
Has anyone also had problems with Payones Credit Card and a Onestepcheckout? Any help would be appreciated!
Cheers, Chris.
---- Edit:
Now I've done the checking of data to enable and execute the order to the end. But when paying by credit card, the check is always performed twice. The first time the system always throws the error "Parameter {} cardexpiredate faulty or missing", even though the expiration date is ok. I suspect that something is wrong with the Javascript.
