@wassim It displays correctly only when the price is set larger than $1. Thank you anyway:)
Here is the screenshot of checkout page.
Here is the screenshot of shop payment settings.
@wassim The PayPal seems work fine, but Stripe is not working at all
BTW the paypal transaction works fine.
Anybody knows why it said," the shop has no payment method". I have already set up stripe. Did I miss some steps?
