Thank you for your response.
The problem is, I don't understand the extension very well. It's two very complex components and I don't understand how it all works, so I actually hired a company to set up HikaMarket. Due to language barriers, they did bot get it 100% working properly.
My set up is actually very simple. I currently have two vendors who will not have any users, they will be their own user. They login, are redirected via a plugin, then select items they'd like to order from their own personal store. There will only be one login for each store, no payment and no shipping. Everything is built and works great, all I need now is a confirmation email to go to the user to conform what they ordered.
I turned on "order status notification" and check the user permissions. Those seem fine now but still no email confirming the order. As admin, I do get the confirmation email but not the client.
Do you have any other suggestions?
