Hello!
1. If I modify the order directly in the order details page and not in the order listing, then the notification e-mail is received regularly (subject and text).
Instead, if I modify the order in the order listing, then the notification e-mail is received blank (no text - subject only).
2. The closest thing to the "Email History is a plugin" I could find is named "HikaShop order history plugin", which was already been enabled (see picture 1.).
If that was not the plugin you meant, here is the list of all the HikaShop plugins I have (can you tell me which one was the plugin you meant, please?):

When I enter the order details (attached picture no. 2), after having clicked the box "Email" in the top left corner (attached picture no. 3) I can see the text the customer should receive (attached picture no. 4), but when I click on "Preview" I actually see no text (attached picture no. 4), as it really happens.
Is there anything to do in order to have a regular e-mail being sent acting only in the order listing?
Thank you!
