Apologies if this has already been asked. I've checked the discussion page for the CategoryTree extension and it looks like the problem I'm having has been reported but I can't see an obvious solution.
I'm running MediaWiki 1.16.0 . I've installed the CategoryTree extension and it does seem to be working. The problem I have is that when there are no subcategories under a category I still get an + symbol next to the category when I think it should display an x symbol. When I click on the + symbol I get the message 'no subcategories'. Also, when there are no subcategories and no pages under the category I do get the x symbol but it's still clickable and after clicking on it it turns into an + symbol. Only after refreshing the page does it return back to a x. Basically I want my categories to expand in the same way as the categories in MediaWiki.org at http://www.mediawiki.org/wiki/Category:Top_level . Has anyone had the same problem as me? Thanks for your help.
Jim
