Installed 2.0 and it immediately broke my theme by forcing both sidebars to the right of the webpage. Reverted bak to 1.9.2 and the theme returned to normal.
The parts of Jetpack I am using are:
Extra Sidebar Widgets
Mobile Push Notifications
I don't understand why this would happen as I am not using, as far as I can see, anything that would mess up the entire theme?
Maybe something in the CSS from Jetpack isn't right?
Any thoughts would be welcome!
