I've upgraded two of my test sites to 3.5 and on both I am unable to move widgets and menu items around; nor am I unable to click on the screen options or help on the dashboard. On one of my sites, the content is still there but when I go to edit the page, the visual editor is empty.
I know this happened as a result of the upgrade since I have changed nothing else and these problems are happening on the only two sites that I have upgraded.
Any help to resolve these problems would be greatly appreciated!!!!
