Hello,
Server sysadmin here.
It should be noted that the server is running CentOS 7 with Plesk 18.0.28.

Composer dependencies were installed via Plesk, and install went OK. Other apps are using it on the server with no issues.

With PHP 7.1 and 7.2, the error shortens that way:

2020-07-03 21:04:09 | Error | x.x.x.x |   | AH01071: Got error 'PHP message: PHP Fatal error:  Class 'Twig_Extension' not found in /var/www/vhosts/reduxroleplay.com/cpredux/app/Extension/TranslationExtension.php on line 7\n' |   |   |   | Apache error

Any help appreciated.
