Hi @maspegren – the error seems to be because of the following code in the plugin:
require_once(dirname(__FILE__, 3) . "/../../wp-load.php");
It looks like the __FILE__ constant on your server returns a path which contains www. This seems to be because of how your server is configured. This thread seems to explain the problem: https://www.php.net/manual/en/language.constants.predefined.php#125170
Let me also consult with our team to see if we can update the code to work without the __FILE__ constant.
