When I click on the edit icon nothing happens. No errors, no post back nothing. I ended up turning on the Console in FireBug and it throws this error:

SP.Ribbon.PageState.ImportedNativeData is undefined
     if ($p0 === 'PageStateGrou...['ItemIsCheckedOutToCurrentUser']) { 

The location of the JS is:

_layouts/sp.ribbon.debug.js?rev=lc6eCMZP6gL5LnuSYh0S6Q%3D%3D

I Googled the top part of the error and found only one person who had this problem. Someone suggested they add ?content=1 to the end of the URL. Tried that but no luck.

Has anyone seen this before? Any suggestions?
