Hi Alec,
I have found another post:
viewtopic.php?f=8&t=8410There it says:
After hitting "Reload locale" on "Home > User > Site Administration > Languages" the translated email-templates appeared in "Home > Journal Management > Prepared Emails".
That worked for me as well.
Thank you for help, after your post I search after emailTemplates.xml and found post that helped.
Regards, Primož
