When a registrated user checks out at paypal for a level upgrade and everything worked fine a very ugly grey page is shown saying something like: “Thank you! You’ve been updated to: Silber Level / Volle Flexibilität”.
Is it possible to modify this site? Or direct to another page?
I read about the success attribut which can be added to the paypal button shortcode. Tried it and it didn’t change anything.
Any advice would be helpful.
