21155	"Prevent warnings in get_the_category from unregistered ""category"" taxonomy"	batmoo	nacin	"{{{get_the_terms}}} can return a WP_Error object if the category taxonomy is not defined (something that sites can do if they want custom taxonomies). This results in some warnings from {{{get_the_category}}} because it assumes that the category taxonomy will always be there and it will always get a valid value back.
