Suddenly the guest/ card payment doesn't work anymore with my simple paypal buttons 'pay now' or 'add to cart'. I add paypal buttons by copying the code from paypal into my WIX website into a box meant to integrate HTML codes. It worked well. I've updated paypal buttons recently.
When processing the payment following error message appears:
Things don’t appear to be working at the moment.
The paypal help article doesn't help me ('My Payments Standard integration isn't processing transactions. What should I do?'
Any idea?
