Not sure how or when this happened. When I am in the Widgets area of WordPress Admin, things seem to be broken. The "sidebar" where you drag active widgets is gone, and none of the "hover" features work. For instance, when i hover over "Pages" on the left sidebar, it used to display a dropdown menu to the right with options All Pages, Categories, etc... Also the Screen Options button doesn't work.
When I am in other admin areas, the hovering works fine. Also I have other websites set up the same that seem to work fine..
I've tried switching themes. I've tried re-installing wordpress automatically. I've tried uploading a new widgets.php page manually.
Here is a screenshot of what I am seeing.
