 * После обновления PHP до 8.1 получаем постоянные предупреждения:
   [08-Dec-2025 
   19:37:17 UTC] PHP Deprecated: setcookie(): Passing null to parameter #2 ($value)
   of type string is deprecated in /var/www/…/wp-content/plugins/wp-yandex-metrika/
   includes/class.ya-metrika-woocommerce.php on line 87
 * **Проблема:** В функцию `setcookie()` передается `null` в качестве значения куки.
   С PHP 8.1 это вызывает предупреждение.
 * **Решение:** Нужно передавать пустую строку `''` вместо `null`, если значение
   куки должно быть пустым.
 * Исправьте, пожалуйста.
