I am also testing an upgrade of a production website to PHP 8.2, and I get this same error message in another portion of the plugin:
Deprecated: Creation of dynamic property WP_Piwik::$statsPageId is deprecated in /var/www/html/wp-content/plugins/wp-piwik/classes/WP_Piwik.php on line 387
I would also appreciate this plugin being updated; I have two others which are also affected by this deprecation.
