Revision as of 05:45, 5 September 2022 by koen roggemans (talk | contribs) (Adding extra possibility why "course module invalid" can appear.)
The ID for the course module is invalid. Please contact the site admin.
For some unknown reason, this happens sometimes when deleting a user. Clicking the back button of the browser and deleting the user again, makes the deleting process continue and delete the user.
It can also happen when "Legacy course files" is enabled. Disabling this can solve the issue.
