I can´t change my online safety and privacy Xbox settings.

(Sorry for any english errors)

I was trying to acess the online safety and privacy Xbox account settings but everytime i go to that page it appears the "The URL may be misspelled or the page you're looking for is no longer available." message. I don't know what to do, i am not in any Xbox family that could block me from changing the settings and my account is 18+, what could be the problem?
