Problem with "PaymentModule::validateOrder - Secure key does not match"? maybe you installed mailchimp module

If you have this problem "PaymentModule::validateOrder - Secure key does not match"

and you have installed the mailchimp module, this is what creates the problem.

Let's go in order.

the mailchimp module sends an abandoned cart, to the customer, the customer clicks and proceeds to order.

If the cart is old there is a risk of not finding the correspondence with the order, so once the customer has made the payment, prestashop does not recognize the two keys "Secure key does not match", generates an error and the customer ends up with a payment made without order in account.

We have contacted the developer of the mailchimp module many times, we didn't receive any reply.
We contacted mailchimp support, but they haven't created the module so they don't give assistance for it.

Hi @RabbitZzZ

no unfortunately, we talked to the Mailchimp support team, they wrote us that they would send this communication to the developers of the module. We didn't receive any communication yet.
