Ref: drlawrencescott.com So, I deleted the theme from my list, downloaded a fresh copy, installed it and disabled all of my plug-ins. The problem is still there. Please note that it’s only not working on the Home menu of mobile devices; if I go directly to another page on the site, the menu works fine.
Note: After trying everything suggested, I just purchased the pro version; while the menu issue is gone, another whole set of more issues arose, so I just reverted back to the free version — just need the mobile menu issue fixed.
Thanks again, Ken
