I am getting error when I am trying use flat file, I am using the same structure as required for the file, and the moodle is locating it but it is showing the following error when running cron.php
Unknown user idnumber or deleted user in field 3 - ignoring line 1
my structure is as following:
add, teacher, username, courseid
usersname is the user login name and not his id such as 3 or 4
courseid is the course id in the course setting and not the number.
I searched for solution before posting but I couldn't find anything
