What is wrong with this 2 lines? im getting Call to undefined function fw_ext_extension_get_listing_categories()
$categories = fw_ext_extension_get_listing_categories ( $atts['cat'], 'models' );
$sort_classes = fw_ext_extension_get_sort_classes ( $posts->posts, $categories, '', 'models' );
Thanks in advance.
EDIT: Here is the function
/**
* @param int|array $term_ids
*
* @return array|WP_Error
*/
function fw_ext_extension_get_listing_categories( $term_ids, $extension_name ) {

}
