Menus no longer drop down
 

Somewhere along the way, I lost my drop down menus - such as anything with a down error like Search or Quick Links. Even my down arrows when composing a new post such as the font size or color. They are now just dead links that do nothing when you click on them.

Because I can't pinpoint when it happened, I'm not sure where I may have screwed it up. :o

Any ideas on what to check first??

Thanks!
