Only Admins are able to change the navigation bar

The option "Top Navigation" can be found in /wiki/Special:AdminDashboard if you have Admin powers.

You should contact the Admins on the Wiki you're on and ask them to look into that for you.

If the Wiki you're on has inactive Admins that haven't edited for over 60 days, you should consider Adoption (see: http://community.wikia.com/wiki/Adoption:Requests)
