Customers er getting "We can't process you payment" error on mylistings

[redwood-denmark]

I've had two customers now, saying that they're getting a "We can't process you payment" error.

Are there any settings on my listing or general setup, that causes this problem, or is the problem on the buyer's behalf?

Apparently you are not alone.
