Of course,
The problem was that the emails were emailed to eight users and had to walk two.
I have solved this in the way described above.
I'm still asking myself, I'm a bit confused from email templates. I understand how to edit, translate, etc.
But I'm mistaken to know which template belongs to the action (I did not find it in the manual.
Which template is the email to the moderator that a new question has come and which template belongs to the email that the user has answered the question?
thank you for your answer
