I'd like to realize 'recurring SEPA-payments' via "Mollie" so I've uploaded the Mollie-library (Mollie JS API client for Node) in the backend-section. After doing so I get lots syntax-errors saying 'Module is undefined'. Anyone have an idea what's going on and how to fix this?
Next to that I'm open for any suggestion to realize 'recurring SEPA-payments' in an easier way without coding. (Paypal is not an option for my audience in the Netherlands.)
