We're getting this error in the log during order processing for a cart on BV Commerce 2015.2.1.1206:

Failed to decode CC. You may need to generate a new encryption key. Exception details: System.ArgumentNullException: Value cannot be null.

The site was moved to a new server and uses Authorize.Net. We re-generated the encryption keys, then checked old orders to ensure we could see payment data.

We're also seeing this warning during the same process:
[Charge] Warning for order number 3928: Authorize.Net Processing Error: This transaction cannot be accepted. [AVS - AVS not applicable for this transaction]


Not sure what else to check.

Aaron, that's exactly what was wrong. After updating the transaction key, the payments processed fine.

Thank you!
