NC 12.0.3 Bug - Unable to edit email templates

Hey all,

i would like to change the text of the emails.
Before NC 12 i was able to edit the mail.php and the altmail.php within the sharedbymail folder but that’s not the case anymore. Can you help me?


could it be that this is kind of the same as
Can't find access to email-templates under nc 12.0.1 ?
