Bug Matomo 3.3.0

Hey Team,

Matomo told me to post this Message in the Forum — here we go:

WARNING: /var/www/virtual/linuslukabahun.de/htdocs/piwik/vendor/twig/twig/lib/Twig/Loader/Filesystem.php(35): Warning - realpath(): open_basedir restriction in effect. File(/) is not within the allowed path(s): (/var/www/virtual/linuslukabahun.de/:/opt/phpswitcher/php7.0/share/pear/) - Matomo 3.3.0 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already)

Is there anything I should do right now?
