(Sub) Menus Not Working

This site capitalistwizard.com has been up for over a year and just recently sub menus stopped dropping down.
The parent menu title is navigating towards nothing “#” and has worked in the past for the pages to just drop down upon “portfolio“

I am working in latest updated “Mantra” 2.3.1 theme. I have deactivated all plugins and the same result

This is obviously frustrating for me and client. Please and Thank You for your responses ??
