Apparently, when customers are making a payment with a Credit Card, and not PayPal, they are getting this error:
PCI :: Security Error
Security Header is not valid
How can we fix this ASAP?

Please contact your PayPal support, and make sure you are using the right credentials for the PayPal Pro account type.
