Roundcube продолжает загружаться при попытке создать новый фильтр с помощью managesieve

Я пытаюсь установить автоответчик для Roundcube с помощью Managesieve и, вероятно, делаю что-то не так. Roundcube работает нормально, / var / log / roundcube / errors пуст. Но когда я пытаюсь создать новый фильтр в области «настройки» Roundcube, где managesieve отображает кнопку «фильтры», и я пытаюсь создать новый фильтр для автоответчика, он продолжает загружаться. Что могло быть не так? Возможно, я смотрю не те журналы?
