Hi Martin,

Before I continue, I would like to say that I have decided not to use the Foliopress WYSIWYG plugin (I am not using any other wysiwyg plugin either). Having said that, here are the Jetpack modules I have activated in case it helps troubleshoot the problem for someone else.

I have WordPress.com Stats, Publicize, Jetpack Comments, Subscriptions, Post by Email, Likes, Sharing, Spelling and Grammar, Omnisearch, Gravatar Hovercards, Contact Form, Google+ Profile, WP.me Shortlinks, Widget Visibility, Shortcode Embeds, Custom CSS, Beautiful Math, Extra Sidebar Widgets, Monitor, JSON API and Enhanced Distribution enabled.
