Dont see checkout page

Hi there,
why I cant see anything in checkout page and is not configurable at all?

Hi there, can you give us some screenshots and possibly the link to your app?

Even if I try with the basic template it doesn’t work.

Have you connected your Stripe for the app?

Not really. I don’t even know how to do it.
Im quite new sorry

No worries, follow the instructions here, I hope it helps:
