This issue might be off-topic from Moodle development. But it is a bit urgent issue. Thus, I am asking this problem to our Moodle experts in this forum.
We are using Moodle 2.1 and am I am getting a Moodle administrator training. After I learned something from this training course, I checked out our Moodle site. In particular, I examined the security overview under reports in site administration.
To my surprise, it says the Frontpage role is critical, XSS trusted users is warning and backup of user data also has a warning sign as in the attached picture.
What kind of action can I take to remove these messages? We are using an external database and self-email registration as an authentication method.
Can you guys give me some guidance?
