    I get an Notice about undefined variable keys on existing taxonomies without alternative URLs:

    Notice: Undefined variable: keys in /wp-content/plugins/hreflang-tags-by-dcgws/includes/functions.php on line 369

    PHP Version: 7.2

    Line 369:

    if (count($keys) == 0) {

    Suggested solution: Using empty($keys) instead of count

    if (empty($keys)) {
