I am unable to add images or edit widgets or edit slugs or even change accessibility options by clicking on 'screen options'.
Basically nothing happens when I click. Even changing the theme to Twenty eleven does not solve the problem. I am using WPZOOM's MONOGRAPH THEME.
All this works fine with IE7.
In console I see this error- ReferenceError: jQuery is not defined
I have been stuck with issue for about a week and I have tried everything including WP re-install.
I think a lot of people are affected by this issue/WP bug and WP support should do something about it.
