Have just upgraded form 1.9.+ to 2.0 everything went well except the blocks on the left side(theme: formal white) drfifts to the right about 5cm. The home page is fine and the course page. Not so lesson pages or theme settings etc.
Alsi I'm not able to change themes - the theme setting brings up a page asking to clear cache and returns the same page ...clear cache.
