What to do if the following error appears during Jetpack installation:
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 403]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/
To activate Jetpack, the xmlrpc.php file must be accessible. To do this, add the following rule to your .htaccess file:
<Files xmlrpc.php> Allow from all </Files>
After adding the rule, disable the Pingback feature in WordPress: http://en.support.wordpress.com/comments/pingbacks/
