Hi, I can not connect with Jetpack plugins, because the xmlrpc.php is blank.
I contacted Jetpack developer, they said you guys blocked my site xmlrpc.php file.
Can you please unblock xmlrpc.php?
If what you are being told is true (and I've not run into that with GoDaddy hosting to date), you'll have to contact GoDaddy support for assistance.
