From CLI, after the command php tools/upgrade.php check I get
Composer detected issues in your platform:

PHP Fatal error: Uncaught RuntimeException: Composer detected issues in your platform: Your Composer dependencies require the following PHP extensions to be installed: bcmath, intl. in /var/www/vhosts/.../lib/pkp/lib/vendor/composer/platform_check.php:47
From phpinfo() it seem that the extensions are availables:
There are probably different PHP configurations for command-line and web-based PHP invocations. Try running php -i from the command line and I suspect you’ll see that those modules aren’t enabled.
