Doesn't transfer to pay?

Question

WordPress

There is a site. https://lemurvpn.com/podpiska/ when purchasing goods, payment methods are selected. and when you click on the buy button, it redirects you to the page of a successful purchase, without payment. Why can this be so?
Earlier on paypal there was a transition and payment

Answer 1

I can't access this site at all. I have it blocked.
In general, this is due to some innovations due to which most of the APIs working on js do not work. And why does it flip? because there is no page, if the payment was made with an error, then the page would be an error.
