Like the users on a previous thread here (http://wordpress.org/support/topic/jetpack-subscribe-widget?replies=10), I'm also having trouble with the JetPack blog subscriptions widget. It seems that all other widgets adopt the CSS except this subscriptions widget, which seems to override the CSS.
Does anyone know how to solve this problem? I'm specifically trying to change the font color of that widget from black to white. Check it out here: http://johnny-chen.com/.
Thank you in advance!!
