Problem arose on upgrade from MW1.16.5 to MW1.18. The + symbols do appear (after making the change at http://www.mediawiki.org/wiki/Extension:CategoryTree#.5Bx.5D_.5B.2B.5D_.5B-.5D_toggles_shown_only_on_the_first_level_of_the_category_tree_view) When the + symbols are clicked the 'loading...' line appears but the sub-categories never load. This happens with MW1.18 with CategoryTree release 44056 (which worked fine with MW 1.16.5) and the CategoryTree snapshot release for MW1.18. This happens the same in IE, Chrome and Firefox. Thank you in anticipation
I apologise: it works fine in Monobook. It doesn't work for me with 'GumaxDD' skin which is what I was using (may be something to do with using very short URLs?). Sorry again.
I should add that GumaxDD was updated to work with MW1.18.
