 * Hello
 * After updating the plugin [Product Feed Manager for WooCommerce](https://br.wordpress.org/plugins/best-woocommerce-feed/),
   this error started to appear:
 * `PHP Fatal error: Uncaught Error: Call to undefined function GuzzleHttp\Psr7\
   uri_for() in /wp-content/plugins/wp-s3-smart-upload/vendor/aws/aws-sdk-php/src/
   Api/Serializer/RestSerializer.php:35`
 * Apparently Product Feed is using an updated version of GuzzleHttp package and
   it’s impacting on your plugin. Can you see if there is an update for AWS or other
   packages, please?
