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

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

How can it be solved?

Thanks,
