we have Magento 2.25 and recently it stopped accepting credit cards. We were originally using authorize.net and when a user enters a credit card number it comes back with an error that says "Please enter a valid credit card type number". This error comes up right below the field where you enter the credit card number. Once you enter the number it happens immediately and does not allow you to checkout. We have tried different cards such as AMEX, Visa, and MC. Regardless of the card type, it returns an error "Please enter a valid credit card type number". At first, we thought it was an issue with the Authorize.net module so we tried different payment solutions. We tried PayPal and it also returned the same error. Any suggestions on what may be causing this issue?
Any help would be much appreciated!!
