I am trying to delete a course and, although WeBWorK says the course has been deleted, it is actually not and I get the warnings outlined by the attached screenshot. Would anyone know what what might be causing this?
It is probably that the web server does not have write permission on the directory /opt/webwork/courses/neil-test/templates/Stat200SPC. This can happen if that directory was created using the command line in linux rather than through WeBWorK.
If you change the permissions or ownership on that directory, then the delete will probably succeed. Alternatively, it's worth checking if the rest of the course was deleted. If so, it may be more efficient to just manually delete the remaining directories.
