That's odd -- have you edited the emails that ship with the system? If you haven't, try manually resetting the emails to their defaults. To do this:
- Log in as Journal Manager
- Go into Perpared Emails (or Emails, depending on your version of OJS)
- Click "Reset all templates" at the bottom of the page
Note that if you have modified the email templates, your changes will be deleted
If this doesn't solve the problem or if you've already customized the emails and don't want to lose your changes, contact me at firstname.lastname@example.org
and I'll look into your situation in more detail.
