Tried to solve this by updating Joomshopping to latest version (4.16.2) - but still not working. It is about: https://marokkaansaardewerk.nl - Going to card and checkout. When clicking on "next" I get following errors and checkout button does not work.
Uncaught ReferenceError: showPaymentForm is not defined
