Greetings!

I was just promoted to the rank of Admin recently on Maken Ki wiki (http://makenki.wikia.com/) and I wanted to start editing  the wiki's MediaWiki:Common.js but noticed that I wasn't able to do so despite having admin rights.

The page only shows the option to "View Source" and is uneditable.

May I ask what should I do to edit it?
