We have a role that is based on the editingteacher role, but slightly restricted.
The problem is with the participants list: The options to select students and choose what format to download the selected participants as a list is there, but when having made the selection it all ends up in a blank page (https://mymoodle.lnu.se/user/action_redir.php)
The downloading works fine for the editingteacher role.
I have tried to find any permission that controls this, but the only permission I can find regarding the participants list is viewparticipants, and that setting is the same for both roles.
I suppose there must be another permission that causes the problem, but I cannot find it.
