Я разрабатываю плагин платежного шлюза WooCommerce с WordPress версии 5.4.2 и WooCommerce версии 3.8.0.

Плагин работает нормально в течение нескольких 3-4 попыток, но после этого я не могу перенаправиться на страницу оформления заказа. Он продолжает перенаправлять на страницу корзины.

Я также проверил журналы, но там ничего не найдено.

Я не профессионал в WordPress.

Плагин имеет живую демонстрацию

Вы можете увидеть код ниже
