Dropdown Menu feature stopped "dropping"

Before I offload my problem, let me just say that at least once a week someone compliments me on the design of my site using Everest Pro! It seems that others like the look of the theme as much as I do. The website is carmenamato.net and the dropdown menu no longer "drops," by which I mean the pages which fall under the menu parent pages no longer show when hovering over the menu. I've deactivated any plugins added since the menu stopped working but none seemed to make the difference. Any suggestions for returning the dropdown menu to normal much appreciated!
