I have installed Moodle 3.9.1 on Ubuntu 20.04.1. Then, I have downloaded and copied coderunner into moodle/question/type folder. Moodle Plugins recognize that I have placed code runner but it shows as Disabled in "Additional Plugins" section. And, it does not show any Setting so I can do something with.
I have reinstalled Moodle and coderunner twice. But the problem is still the same.
Can anybody suggest anything?
