Hi @aweissinpsyde,
Thank you for your answer. We have reinstalled the plugin and that did the trick for most users. Today we had a few people that needed to do a recurring payment. The recurring payment did not work immediately, so i did a process renewal in Woocommerce. This trick had worked before on some other subscribers, but not this time. This time i got the following error message:
Error updating some information: A “_mollie_customer_id” value is required.
Do you have any idea what do do with this error?
