Hi, the jetpack subscription widget is working perfectly but when I try to use the [jetpack_subscription_form] shortcode on a page or post the output is blank. When something is activated usually it will display the shortcode as text but instead it's displaying nothing.. I've disabled all plugins etc and tried several other things, I've taken a look at the subscription.php file and noticed there is not a closing php tag (?>)at the end of the file but when I try to add one the shortcode reverts to showing as text on the page.
I'm using the smartscreen theme.
Thanks,
Zach
