I have an event setup with two pricing options one for members and the other for non-members. The members price is $0he non-member is charged $35. When someone selects the Member option at no charge the following error comes up:
Payment Error Response:
- Error: Could not find payment information
If they select the non-member option the payment block loads and the registration processes fine.
This is CiviCRM 4.7.23 with WordPress 4.8 and Stripe payment processor (ver 4.7.1)
