The upload course area is not for restoring a backup file. That is for creating courses with a csv file. If you want to restore a backup, go the front page of your site and select restore from the admin menu.
Dear Emma, Thank you very much! I already resolved this issue, and everything is working good
Thanks all!

Backup file should be .mbz not .csv and shouldn't get as far as analysing the columns before telling you its an invalid file type.
Is the file actually a Moodle backup or is it a csv file (list) of courses and their details for the upload course tool itself?
Oh that's interesting Richard - you just made me go and see what happens when you upload a file that isn't a CSV file. I just uploaded a random png image file instead, first thing I found, and I got the message "there is something wrong with the format of the CSV file - number of columns not constant". I think this is misleading if you have mistakenly uploaded a file like an .mbz. I wonder if we should change that wording to clarify? (I will go and change the "More information about this error" in the meantime...
Thank you so much for your support.
Thank you so much!
