I have exhausted all my options and neurons here...
I have 2 courses: Leader 1 and Leader 2.
The problem is that Leader 1 course started to show some blocks on it's main page that it was not supposed to (like the admin block with the grade/profile links on the left in the printscreen).
I took a printscreen from both courses (accessing as a teacher) and you can see that on the left in Leader2 there is no 'admin' block showing and on Leader 1 it has.
Where can I set which blocks are shown for a determined role ('teacher' in my case) on the course main page??
thanks in advance,
