No order confirmation email after purchasing from one shop - Multistore

[banan_44]

Hello, I am using PS with MultiStore function. I have 6 shops (each shop have an unique domain) in my Prestashop. Recently I have noticed that when someone orders an item from one shop (domain) Prestashop does not send the order confirmation email (but I receive a New order email). My other shops (domains) do not have such problem, the customers receive the confirmation emails with no problem. This problem exists only in one shop. Does anyone can tell me where can I change that? I want all shops to send the confirmation emails.
