Forum:Category problem

I have been experiencing Category problems on the Nitrome Wiki for some time now. Whenever I want to put in a category on an article, I have to put it in manually by typing due to the "Add Category" button not responding when I click it.

I also cannot move or delete categories from an article as the small buttons also don't respond. -- 20:12, September 6, 2010 (UTC)
