On my site www.fotocomefare.com I've been using the same menu for months.
It is a Wordpress menu I assigned to the %cats menu. In it, I recreated the category structure.
It used to work, that is, when you hovered over a category name, sub categories would drop down.
Today I discovered it doesn't work anymore. Down arrows are shown and hovering changes the items background color. However no subcategory list drops down.
I tried W3 Total Cache, supposing js minification was the culprit, but it isn't so.
I turned off Animate Category Menu Bar but it didn't change anything.
I'm using Wordpress 3.3.1 and atahualpa 3.6.4. What can I do?
