Hi @jaapjvh,
Can you ask your merchant to contact our Integration Team to find the cause of this problem?
FYI: In a vanilla WooCommerce you land on our iDEAL QR payment page.
Hi Maxwell,
We would like to help you with this error. I can schedule a dev debug block for you. I will send a mail to plan this to the trusted mailadres for this website.
Kind with regards,
Berend
