Forum:MediaWiki Page Editing Help

On my wiki, I can't edit MediaWiki:Wikia-navigation-global, but I'm an admin there. It says I can't perform the action. What's wrong?

 * You cannot edit that page because staff made themselves the only ones able to edit it. 17:20, October 12, 2011 (UTC)


 * That is a staff only editable feature, and against the Terms of Use to change. -- 17:20, October 12, 2011 (UTC)


 * But you can add new items to it with JS --Ciencia Al Poder (talk) -WikiDex 17:22, October 12, 2011 (UTC)


 * Can someone give me the base code for additions? Just without page names and display text and the like.
