PayPal: We're sorry, something went wrong with that

when I pay by PayPal, always return this
I don’t know what happened

Are you seeing that error on PayPal’s site or Cloudflare’s?

on cloudflare. In fact, the payment did’t transfer to PayPal. Because I had contacted PayPal, they said had no record
