Also please note that your custom thank you page needs [accept_stripe_payment_checkout][/accept_stripe_payment_checkout] block where you need to show successful payment information.
Yes, I have a custom thank you page, which normally displays fine, but when trying to display the error, it never renders.
I will await this plugin update and see if it fixes the problem. Thank you for responding to me.
Did you clear the browser cache before trying another transaction?
Yes. Tried in multiple browsers also. Same result. According to the log, it seems more like a hard error.
