It simply require to clean the session/cookie.
The guest checkout is stored in the Joomla session. So if you clean the cookies or do actions like login/logout, the Joomla session will be purge automatically.
Do you suggest to end users to clean cookies if they want to change their email?... Or I need to learn php, hikashop & joomla internals to implement this "logout from guest mode" button myself? This functionality must be a part of the checkout process, otherwise 99% of those users who want to change email will just leave our shop forever.
The main reason I paid for hikashop essentials is the guest checkout mode. And it turns out to be just partially implemented!
