 * Hello, I really like your plugin and it is working great but when I try to update
   to 3.53 from 3.52 then I am getting the following error.
 * Plugin could not be activated because it triggered a fatal error.
    Fatal error:
   Cannot declare class Firebase\JWT\JWT, because the name is already in use in /
   hermes/bosnacweb01/bosnacweb01aj/b676/ipg.daronwall30230/wp-content/plugins/customer-
   reviews-woocommerce/firebase/src/JWT.php on line 22
