Чтобы деактивировать плагин в вордпресс надо зайти по FTP в папку с плагином и переименовать по этому пути эту папку /wp-content/plugins/wp-recall например wp-recall-2 укажите. Плагин деактивируется.
После, не забудьте вернуть как было. Это важно. А то у вас может быть потом несколько версий плагина.
Это вы обязаны знать как администратор своего сайта. Т.к. это может быть не только WP-Recall, но и любой другой плагин. Вордпресс предоставляет этот способ
Вот что мне дала техподдержка
