I cannot upload cohort information for existing users using CSV. I have looked at both the links:
https://docs.moodle.org/34/en/Cohorts#Uploading_users_to_a_cohort and
https://docs.moodle.org/34/en/Upload_users#Cohort_membership_assignment.
I have already tried with column name as "cohort1". Every time, I upload a CSV, I meet with the following error:
"There is something wrong with the format of the CSV file. Please check that it includes column names."
Moodle version=3.3
Thanks in advance.
