Я написал проект где можно добавлять и удалять студентов из таблицы где их список, так вот я хочу сделать так, чтобы на главной странице когда запускаешь страницу была страница где юзер должен сделать вход через логин и пароль. Я вроде все правильно написал, но он ругается на неправильный контекстный путь. Можете посмотреть, что не так в моем проекте.
