De-register custom taxonomy

Hi guys,

I was testing out custom taxonomies and added a test taxonomy to my site using the code below. But now I can’t get rid of it! If I just delete the code, I get the error ‘Invalid taxonomy’.

Can anyone tell me how to delete it please?? Thanks 🙂

‘function people_init() {
// create a new taxonomy
register_taxonomy(
‘people’,
‘post’,
array(
‘label’ => __(‘People’),
‘sort’ => true,
‘args’ => array(‘orderby’ => ‘term_order’),
‘rewrite’ => array(‘slug’ => ‘person’)
)
);
}
add_action( ‘init’, ‘people_init’ );’
