"This cart mixes African and international producers"
Why you can't checkout from multiple producer types.
What happened: your cart contains items from both African (Flutterwave) and international (Whop) producers.
Try this first: remove items from one producer and checkout separately. Complete one order, then start a new cart for the other producer.
Note: international (Whop) producers must also be checked out one at a time.
