I upgraded to 3.5 and have Thesis theme running. Front end does not have any issues, but there are major issues everywhere in the backend. Ajax menus, drag and drop and other features like that have stopped working. For example when I hover over "dashboard", it should show the submenu, it does not display it now... If I want to drag a widget into sidebar, it does not happen.
I jetpack, when I click on learn more, the drop down box used to come, not it does..
I suppose all the dynamic elements have stopped working..
