In checkout page we do find an error as UNAUTHORISED, After completing all the checkout details still it shows this , we have tried by deactivating all the plugins but not working still . Could you please have a look.
You have to update the theme and plugin both- theme version Dokan 2.2.1 and plugin version 2.4.5. If you are using cash on delivery then in the latest version customer will be able to purchase from 2 different seller's product.
