I'm trying to figure out an issue on a WordPress site with sub-menus not appearing after an upgrade to WP 3.9.1. The site -- accessible here -- is using the Zeus theme (v. 1.1.0) and it appears that the sub-menu behavior is handled by "jqueryslidemenu.js".
Upon upgrading WordPress, the loaded version of jQuery changed to 1.11.0 and it appears that this theme was developed with an older jQuery version, so I'm wondering if that might be at the root of the issue. Interestingly, with the help of Firebug, I can see that the sub-menus are being created within <ul class="submenu">
-- say by hovering over "About" in the main navigation menu -- although they are just not visible. Thus I'm hoping there is an easy solution via a JS/CSS edit.
tags in your Google Analytics code. You might also try replacing the $ in the document ready function in jqueryslidemenu.js with jQuery as outlined in this answer: http://stackoverflow.com/questions/7975093/typeerror-undefined-is-not-a-function-evaluating-document
