Widget Menu Stopped Working (no plugging updates)

Hello,

Having recently installed the Enfold theme, I immediately fell in love with its versatility. Early this morning, I inserted a button short code within a custom widget, which I then assigned to the header (Via the instructions found here: http://kriesi.at/documentation/enfold/adding-a-widget-area-to-the-header/ ). Everything was working fine, until about an hour ago.

Now, when I go to Appearances—>Widgets I CANNOT do the following:
1). Activate any new widgets (via drag/drop)
2). Obtain a drop down from a widget
3). Click on either of the “Screen Options” and “Help” buttons in the upper right corner of the screen (i.e they’re frozen)

Oddly enough, I can (Yes):
1). Create a new Enfold Custom Widget Area
2). Manage the widgets in the 4-footer columns via the “Manage with Live Preview” button

Looking for an easy fix, I disabled all of my plugins and cleared my caches, but that didn’t work. I disabled the Enfold theme and activated a random WordPress theme to see if the issue was theme-related. Interestingly, the Appearance—>Widget menu worked perfectly in this other random, freebie theme. So, in assuming the problem was either Enfold-theme or user (me) related, I went ahead and deleted the Enfold theme altogether, reinstalled it back onto wordpress via zip, and activated it. Then, I tried to access the widget menu on the Appearance—>Widgets WordPress pg again. But it still doesn’t work…same problems persisted.

If anyone has some time, I greatly appreciate a reply. I love the Enfold theme and would hate to have to go with another one.

Thanks in Advance,
