Minecraft: Появилась проблема с плагином X-TimePass и другими подобными плагинами.

Я создал свой сервер в майнкрафт по тематике рп. Я решил войти на него со второго аккаунта, и когда я пишу команду /pass, мне пишет: an internal error occurred while attempting to perform this command
Перепробовал все способы решений этой проблемы, не помогло! Вот ошибка из консоли:
