Same here.
THEN I deactivated one of my plugins and the widgets page re-appeared!
Could it be a rouge plugin that doesn’t like the WP upgrade?
I’ve upgraded to 3.4.1 and now I cant edit the widgets page.
All was running fine until then!
Same here.
I recently upgraded wordpress 3.4.1 and now when I go to the widget page in
appearance, there is nothing!
So i can’t edit, update or delete the plugins that are on my site!
This has not happened before with an upgrade 🙁
What can I do?
