There is an unexpected error while moving to the secured page to pay by credit card on the website of Muse Press. We are now under the investigation of the causes. We are sorry for the inconvenience. If you are in hurry, please select ‘Paypal’ as a payment method. However, if you don’t have your own PayPal account and you can only pay by credit card, please contact us (firstname.lastname@example.org). We will send you a secured invoice to pay directly by credit card. Normally this works without any problems.
