I'm still waiting for a reply from the theme developer..
In the meantime, please go here.. my url /home/demo-home-3/
This is my old “home page”. You can see the search bar below the menu on the center of the page. If you want to recreate my problem you can look at it from an iPhone. Shrinking down the browser to mobile size doesn't show problem/errors unless you look at the java script on the page.
Sorry for not posting the entire url. I don't want google to pick it up from this page.
