I updated a couple of my sites to 3.4, only to realize that the update royally broke the dashboard. A few things work, but I cannot get it to function enough to finish s post.
The main flyout menus on the left don't pop out, meaning you can't access anything inside them. You can only click the button and me taken to its' default page.
The post editing the wiziwig does not work properly. For example clicking the add link or add image button does nothing. Likewise for switching to HTML editing. Some button do work, like adding bullets, but I can't get a post completed with it as too much is broken.
The front end seems to load up fine, but I'm once again kicking myself for updating to the latest version so soon, as I can't even finish my posts now.
Interestingly the flyouts in the top overlay bar (the grey one that also shows on the front end if you're logged in) does work. Not that that helps me post, but it seems it's not simply a JS issue.
I HAVE tried de-activating ALL plugins. No change. I have also tried activating to the latest version of the 2011 theme. No change. I have tried in Firefox 13, Safari and Chrome. All the same problem.
