I would like to have a look on the code of activities' validity concerning the capacity "accessallgroups". Where should I find this code segment ?
The problem is that possessing the "teacher" role I can view the activities of other groups even when the capacity "accessallgroups" is prohibited. With the role student, this capacity really does its job. Whenever granted to student role, students can see activities of other groups (exclusively with that capacity)
Many thank in advance
