WPP generic 10001 internal error

Ah, the dreaded in-dechiperable 'something's up' error from PayPal.

I have a test account ( with generic WPP setup and default gateway.

I'm trying to get through to the receipt page so I can do style it but I never get past the error message:

"There was an error processing your payment: (10001 Internal Error) Internal Error'

I'm using the 4242.. card number.

    Honestly... PayPal's sandbox is both awesome, because it's crazy powerful, and lame, because it's slow and (in our experience) inconsistent.

    Good news though, to style the receipt pages, all you need is one receipt. So I'd set it to for now, run a transaction, then you can always re-access that receipt from the "print" link in the transactions page in the admin.

    Does that help?

    We were told recently by PayPal that the 4242 number will not work on the sandbox. You'll have to follow their steps for generating test card numbers. More info on that here:
