How to Move Forward After Switching Stripe Accounts
WP Simple Pay will automatically sync your payment forms when switching between test and live payment modes. Unfortunately it cannot sync payment forms or tax rates between Stripe accounts.
If you’re seeing the unit_amount error in your site console, or prod_ not_found when saving your payment form, this indicates your payment form’s price options cannot be found. This can occur if you have directly modified items within the Stripe dashboard, causing the data to become incorrectly synced. You will need to recreate the payment form as indicated above.
