Hello,
I'm trying to test our the Simplify credit card checkout with Sandbox mode enabled. I've been trying to test with fake credit card numbers but I always get this error message:
"Please make sure your card details have been entered correctly and that your browser supports JavaScript. Developers: Please make sure that you're including jQuery and there are no JavaScript errors on the page."
When I opened up my Chrome browser console to check for JS errors, I got "Uncaught TypeError: Cannot read property 'payment' of undefined".
Any ideas on what is going on here and how I could fix this? Thank you!!
