Conflict with my Credit Card Payment Plugin

Since I installed the Cleantalk Anti-Spam Plugin my customers can’t get to the successful payment page when using the creditcard payment option. Instead the following error code appears after the payment:

{ “result”:{ “code”:”200.300.404″, “description”:”Invalid or missing parameter”,
“timestamp”:”2023-03-24 11:01:51″ }, “buildNumber”:”20141216-153400.r1.static”,
“ndc”:”w911idipyansl5qu9gxbixj0ob3cx7bu”}

The creditcard plugin is called “Open Payment Platform” (OPPCw).
The problem is, the payment-transaction comes through, but the WooCommerce system treats it as “failed payment” and also the customer then gets a false “order-canceled” email.

I already deactivated all of the “WooCommerce” options in the Cleantalk plugin but it does not help. Only when I deactivate the Cleantalk plugin as a whole, the creditcard payments start working again.

Anybody know a solution to this or experienced similar problems?

Thank you very much in advance!
