I think the problem may be due to upgrading this theme... Totally happy to downgrade, but don't know how!
My categories are no longer playing ball. New ones don't show up at all, existing ones that were fine as subcategories do not want to be subcategories any more.
Hope someone can help, as I don't really want to change the theme, but this has made the site unworkable.
