Hello, please help me.
I just upgraded my moodle to 3.9. but there is a missing course overview from disk.
Then because the course overview is missing, I can't reset the dashboard page to default, when it's reset there is an error like this:
I'm really confused what to do, this course overview plugin disappears from the /blocks directory and when I copy from backup to /block it still doesn't run.
Please help me.
