the server textures setting is gone.

a creative server, edawg878.com, has a server texture. When I asked how to turn it off, the admins said, "options>video settings>server textures." When I opened video settings, and every other form of settings, there was no server textures button or command. I am not sure why it isn't working in 1.7.9, because it has been working using previous versions. I know this for a fact because I have had to turn it off on a number of different servers.
