I can add new friends through xbox.com, and also can message friends. However, on my Xbox, all of my friends have been deleted and I can't readd. It says I have family settings (which are off), and that I must ask my parent to add friends. I haven't been on in awhile and I solved my payment problems, and everything is fine. I've tried restarting the Xbox as well and nothing is helping. Why is it doing this?
