YOu guys are using 169 beta with Cocoon plugin? it barely works now with latest update for 168, and its probably gona be broken with the next c2 stable. Keep 168 stable until you are sure that everything works to update to next stable, beta is a no go.
For now i recommend 168, with the latest update from github cocoon plugin, they updated it yesterday so full screen banners work too, and compile with 1.4.7 , 2.0.0 is unstable for now
