I run online stores and since the latest update the customers are not able to pay with credit/debit card anymore, they get this error message: “Error processing checkout. Please try again.”. This also resulted in many failed orders and many lost sales. I tried to disconnect the PayPal account and connect it back, still the same error message. I had to switch off the PayPal Card Processing option and waiting for your reply.
The issue seems to be with the PayPal Card Processing option
For all that are having issues what is working for now in WooCommerce setting payment tab. Turn off PayPal Card processing. with Pay Pal still active this for me customer still have option to pay with PayPal or credit card. hope this helps. This has been such a faulty plugin. The PayPal gateway was much simpler with less issues too bad they are discontinuing it. The really should second think it.
