In MOODLE 1.9, I was able to prevent Parents and Students from viewing the People block on the Front Page by clicking the Assign roles icon for the People block and then setting View block to prevent for the roles I wanted to prevent viewing block.
In MOODLE 2.1 when I click Assign roles in the People block, I got the message "You are not able to assign any roles here".
I want to prevent parents and students from seeing the People block on the Front page in MOODLE 2.1. Does anyone know how to accomplish this?
