If you are seeing some options grayed out, most likely this means that you're logged in using a Web ID that doesn't have any hosting services under it. If you log out and log back in using a Web ID that has hosting services associated with it, you should see your panel sections come back.
If you're not sure what that Web ID is, contact support with your domain name and they'll let you know what to do from there.
