today we had an interesting situation. We have 3 stores, all with guest checkout enabled. Today (only) 1 store suddenly reported "no guest checkout available" messages in the last step of checkout.
After some digging in Google there appears to be a relation between this error and the
Persistent Shopping Cart. If we disable
Persistent Shopping Cart the Guest Checkout works again.
we enjoy having persistence turned on, but how can we prevent this situation where
no guest checkout available breaks our conversion?
Is there a way to fix this and still have
Persistent Shopping Cart turned on?
