This error message appears when a file is uploaded to Site administration>Courses>Upload courses and the file is either:
- an incorrectly formatted .csv file, in which case, please check Upload courses
- a SCORM package, (such as from Captivate) See SCORM settings
- a completely different file such as an .mbz or .tgz file (a Moodle course backup)
Note: If you see this errror when uploading an .mbz or tgz file, you should be using Course restore instead.
