parsererror
I have just updated (CiviCRM 5.38, mjwshared (Payment Shared) 1.0, and Stripe Payment Processor 6.6) and now payments are failing with 'parsererror' (as an Admin with test payments) or 'error' as a user with a real payment.
Access AJAX API permission has been given to all users, I have enabled javascript and webhook debugging but there is nothing obvious (though I am reaching the extent of my knowledge).
Looking at the Stripe logs I can see for times when I have submitted for pre-approval etc: 200 OK POST /v1/payment_methods
How can i debug further / resolve the issue? Many thanks, Christopher
