I am also having the same trouble in checkout.
I have attached PayPal since among the options for payment processor, only PayPal is the one applicable in our country.
However, when I do a test transaction using a dummy subscriber’s account, it routes to the PayPal’s page with an error “Things don’t appear to be working at the moment. Please try again later.”
I would need a solution as I couldn’t sell a course if this is the case.
Does this require a plugin to integrate with PayPal of was it just the built-in PayPal option you have in this LMS?
Please help.
Thanks.
