sandbox payment not working in Braintree Posted Tuesday at 10:59 AM I install latest braintree 2.01 on oscommerce 2.3.4. When test on sandbox, i always get this message 'There was a problem processing the card. Please try again and if problems persist, please contact us or try another payment card or method.' i have disable cvv verification, 3d secure and create token and use 4111 1111 1111 1111 or 5555 5555 5555 4444 and another visa and master card recommended by braintree. No of them working. Anyone face this issue?
