We have a problem with our Menu. Sometimes the drobdown menu are not available. That report us many people and we have the problem to. We have test it with IE and Firefox.
Yep, I have the same issue. Did you try logging in as admin, previewing the page? For me that works, but obviously it’s not helpful as users are not admins.. 🙂
The dropdown menus fail if there are JS issues on your site.
Debug your site with developer tools (F12 in most browsers) and see if there are any conflicts between the theme and plugins concerning JS.
