"Sorry, this activity is currently hidden" displayed for students

Hi,

I've encountered this issue with students. They don't have access to the test and the error "Sorry, this activity is currently hidden", even if I change permissions in Course Administration.

Hiding/showing the activity in the course also didn't help. 
Can you please help figure out how to fix it?
