Hi I setup a wordpress site and installed the Jetpack plugin. It used to work great but I am now unable to connect to Jetpack. I always got this error : Error Details: The Jetpack server was unable to communicate with your site [HTTP 404]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.com/support/ So here I am, how to solve this issue ? Thanks
