I have a website for which I used Moodle 3.11.2 (Build: 20210729)
But I'm having an issue which is when I add an assignment, the students can't submit thier assignments ( the submit assignment button disappeared), even though all the settings are adjusted
This is the plugging page with the first option "assignment"
But I don't have any of these additions in my website
Now how can I add these options, so the students can submit thier assignments
