MarketPress PayPal Error 10001

MarketPress 2.4 / WP 3.3

When I attempt to pay with PayPal I get this error:

10001 – Transaction failed due to internal error – Internal Error

I have tried two different live accounts with no success. I haven’t tried sandbox because the sandbox registration is down for now.

    Hi jbfighter and first off, welcome to WPMU DEV!

    That error is usually an indicator that the credentials you’ve entered are incorrect. Could you please double-check and verify that the credentials or account info you’ve entered are indeed correct?

    Sometimes folks will have sandbox credentials entered for a live account or vice versa as well. Could you check that you’ve got the proper credentials setup for this particular account?

    I was able to get the store working with a different plugin, but I would still prefer to use MarketPress if I can get it working with these credentials. I updated to 2.4.1 and now I am getting a different error message with the same credentials.

    10400 – Transaction refused because of an invalid argument. See additional error messages for details. – Order total is missing.
