PayPal accepts the payment when in sandbox mode, but won't work when using the production setup. https://www.inertiasoundsystems.com/store/checkout/ The error link is this: https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=e4b90e72aaaf&code=GENERIC_ERROR&mfid=1511293322701_e4b90e72aaaf but GENERIC_ERROR is generic (pun intended), so not sure what to look for. In case you don't want to go over the trouble of creating an account, here's the generated button code: <div id="paypal-button" style="width: 200px"></div>
