I went on my site this morning to check some things and noticed the drop-down menus are not working. I updated to WordPress version 3.4.2 yesterday and pretty sure everything was working. I updated my widgets this morning and shortly after is when I noticed the drop-down menus were gone. Not sure if the updates were the cause. I viewed the source code and to me it looks like the code is still there. I just manage the content of the pages and do some basic html updates, nothing too advanced.
Any ideas what is causing the drop-down menus not to work?
