Don't fogot enable DoctrineCacheBundle in your AppKernel.php - See https://symfony.com/doc/current/bundles/DoctrineCacheBundle/index.html

Your own modifiers

You can add/override modifiers by easy configuration:

phpmob_twig_modify:
    modifiers:
        xss: # a modifier name
            enabled: true # default true, toggle enable/disable this modifier.
            class: \PhpMob\TwigModifyBundle\Modifier\HTMLPurify # static class or any service
            method: purify # service method that's allowed to accept `[$content, (array) $options]
            options: # are array options you want to past into your modifier method - `\PhpMob\TwigModifyBundle\Modifier\HTMLPurify::purify` in this case.
                Cache.SerializerPath: "%kernel.cache_dir%/htmlpurify"
