Changes above removes it completely, only for yourself, and only for the wikia you put it on. Together with all the other people here, I agree and support it being only used on your personal page - and I confess I might not have been completely subtle with the above info. I really only intend to help those people who don't want it there, and those who know the wiki they're on good enough to not even need the search funtion. I know I do on my main Wiki.

as for the old, you could bring it back by replacing the contents of the above referenced Class with the correct HTML, I think it should work, unless Wikia changed some supportive functions. Can't help you with that though.
