Ubuntu 16.04 tomcat 8 менеджер веб-приложения нет доступа

У меня была проблема с тем, что пользователь и пароль заходили в веб-приложение менеджера, и попытался исправить его, отредактировав файлы manager.xml и host-manager.xml. И теперь я даже не получаю приглашение к входу в систему и проверяю логи, и он не запускается. Я взорвал это.

Надеюсь, кто-нибудь подскажет мне где-нибудь начать с файла журнала, который я публикую.

Спасибо

Морган
