Lost functionality since 2.8 upgrade

Just upgraded to 2.8. I always do a manual update but I took the easy way out this time and it messed the functionality up a little bit, I tried auto upgrade from within in the admin panel.

Anyway.. nothing has happened to the site, the blog runs well externally after the upgrade however I notice loss of functionality in the admin panel.

The “Quick Edit” tags do not work, the Expand and Collapse on the Menubar does not work, the Drag functionality on the widget page does not work or on any object.

After noticing these problems I did a manual upgrade however that did not solve the issue either. I also cleared cache, cookies, etc.. on my browser and tried again but no luck. This happens on all browsers.

Plz help!
