"Email Template Not Found" Error
Tried to add an account and/or assign a course and you get an "Email Template not found" Error.
There is not an associated email template for the role you are trying to create or assign to.
Visit your "Email Template" menu item and ensure that the email template you are trying to use has the role listed.
For example below, the Contractor Invitation email template is only assigned to the "Contractor" role.
