Q: Что я сделал?
О: Я решил обновить этот проект, используя:

php composer.phar self-update
php compser.phar update

Результаты по запуску проекта на хосте:

Предупреждение: require (/home/tufoo/public_html/blog/vendor/symfony/symfony/src/Symfony/Component/Intl/Resources/stubs/functions.php): не удалось открыть поток: такого файла или каталога в / home / нет tufoo / public_html / blog / vendor / composer / autoload_real.php в строке 54

Неустранимая ошибка: require (): сбой при открытии обязательный ‘/home/tufoo/public_html/blog/vendor/symfony/symfony/src/Symfony/Component/Intl/Resources/stubs/functions.php’ (include_path = ‘.: / Usr / lib / php: / usr / local / lib / php ‘) в /home/tufo/public_html/blog/vendor/composer/autoload_real.php в строке 54

Я на cpanel, php7, Litespeed.
