I got this message:
“Your website needs to be publicly accessible to use Jetpack: site_inaccessible Error Details: The Jetpack server was unable to communicate with your site [HTTP 500]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/”
I have tried everything, deactivate all plugins, deinstall the jetpack and reinstalling it, nothing works. Helpp, what should I do?
