WordPress: PHP Warning: Cannot declare interface Twig_LoaderInterface

Hi,
After updating Matomo to 3.10 there is a conflict that disturb homepage display.

Here is the log:

[03-Jul-2019 13:50:18 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in /home/username/www/wp-content/plugins/addon-so-widgets-bundle/cmb/init.php on line 746
[03-Jul-2019 13:50:19 UTC] PHP Warning: Cannot declare interface Twig_LoaderInterface, because the name is already in use in /home/username/piwik/vendor/twig/twig/src/Loader/LoaderInterface.php on line 61
[03-Jul-2019 13:50:19 UTC] PHP Warning: Cannot declare interface Twig_ExistsLoaderInterface, because the name is already in use in /home/username/piwik/vendor/twig/twig/src/Loader/ExistsLoaderInterface.php on line 33

By disabling WP-matomo the display will return to normal.

How can it be solved?
