Hi!
I've got today error on checkout with credit card. "Error 10542-This transaction cannot be processed. Please enter a valid email address" Later same AmEx card accepted on PayPal Terminal with no problem.
At the same time customer with VISA card checked out with no problem.
I did try to use different email address for this customer/CC - same error message.
I did not add/modify any modules on checkout process reCaptcha only on acount create page.
Please help to find where is the error from.
Thank you.
