В админке ошибка "[phpBB Debug] PHP Warning: in file [ROOT]/vendor/twig/twig/lib/Twig/Extension/Core.php on line 1266: count(): Parameter must be an array or an object that implements Countable"

Версия движка 2.0.4 (phpBB 3.1.9)
База данных MySQL(i) 5.7.21
моды и расширения не установлены.

При входе на форум получаю вот такое:
