There's something wrong in the template Navbox with collapsible groups. It worked in my one wiki, it doesn't seem to work in my other wiki, although I copied the templates from the first wiki. I have also copied the code from the MediaWiki:Wikia.css. I don't know why it won't get collapsible. Help?
