We are also facing the same issue on our website – tested for ‘Testing Only’, Authorize.net, Stripe.
However, if I use a 100% discount code the transaction goes through.
In our case, we are using following add-ons:
1. Add member from admin
2. BuddyPress Add-on
3. Cancel on Next Payment Date
4. Developer’s Toolkit Add-on
5. Email Templates Add-on
6. Member Homepages Add-on
7. Multiple Memberships Per User
8. Series Add-on
9. Shipping Add-on (This was added after we noticed the issue)
10.
