My suspicion is the Disqus installation (hence deactivated by still appearing in the comments area) is at fault but I figured it best to ask for a few more opinions. Upon the initial installation of Jetpack, the sharing function was 100% working as expected. Within 24 hours, the email and print options failed and even report a "msg=fail" in the url but that's it.
Is there a reason why the email and print would fail, but not the other sharing functions? I'm befuddled.
