Paypal Issue.

Problem: “In the last page when you click validate, it shows a page with code inside.”

 

Solutions:

Check first if your currency is accepted by Paypal:

If it’s accepted, you have to know that you can’t create free plans for now, and the error could come from the fact you send a null amount to Paypal, and that leads to an error. Remove your free plan, and create paid plans.

If it’s not the problem, you should be sure your Edition is updated. Check if there is a new update for your Edition:
