PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class WunDBManager does not have a method "addNewBlog" in /wp-includes/class-wp-hook.php:324
Action location: /plugins/wpdiscuz-user-notifications/wun-index.php:41
"add_action("wp_insert_site", [&$wunDBManager, "addNewBlog"]);"
Should that be "onNewBlog" by any chance?
