Support for Divi 2.4 Theme

Hey there. I’ve been using your plugin on one of the sites I manage for several months and it’s functioned great! Unfortunately, it’s no longer working with the most up to date version of the theme I’m using (Divi by Elegant Themes). I was wondering if you could take a look at my development site to see what may be the issue. I’ve disabled all other plugins.

Development site with most recent version of the theme (2.4.5.1):
http://developer.vcfphoenix.com/

Active site with previous version of the theme (2.3.2):
http://vcphx.com/

I only have the first navigation item set up to display anything on the development site, but its still not showing any dropdown.

Thanks
