Forum:JS stopped working since update + change 'On the Wiki' slightly

Since the Wikia update a few days ago, this javascript on my wiki is not longer working. http://doctor-who-collectors.wikia.com/wiki/MediaWiki:EditBar.js It's not an IE problem; it will no longer work in any browser.

Also, is there any way to change the 'On the Wiki' at the top? I just want to add 'Recent changes' and forum links etc.  Tardis1963   talk  04:48, October 8, 2012 (UTC)
