All taxonomy term paths default to the www.example.com root directory
If you have pathauto module installed, you might want to check the taxonomies aliases go to "/admin/config/search/path/patterns" and look for the old Vocabularies and see how the path is setup. moreover you might want to delete all aliases and do a bulk update for theme "/admin/config/search/path/delete_bulk" then "/admin/config/search/path/update_bulk".
