 * Здравствуйте.
 * Вы используете последнюю версию нашего плагина? Эта ошибка видна на самом сайте,
   или вы смотрите логи?

 * Добрый день! Последняя версия, эта ошибк видна на сайте. Сначала появляется она
   на белом фоне, потом прогружается весь сайт и ее не видно.

 * У вас у единственного такая ошибка. Скорее всего конфликт с другим плагином.
   
   Если это не влияет на работу сайта, то отключите режим отладки WordPress, чтобы
   ошибки не отображались.
