Hi @califer,
I’ve just checked into this and it looks like we still need a tweak on the issue linked above – an additional commit should be added there shortly. This will grant better access to the Users & Roles area for administrators who are not journal managers.
In the meantime, to work around you this, you can either use a Journal Manager account or create new entries in the user_user_groups table to grant access to the Journal Manager role to your Administrator user.
