How to fix Updated Wordpress to 3.9.1 featuring Modest theme from Elegant Themes.

I updated a customer site with no child theme or back up. The Home page is nowhere in the pagres directory for edit and the three columns below the carousel reveal acutal page detail, etc. Can I revert to the prior version of Wordpress before 3.9? How do I find the Home page for edit?

The Home page is in Menus but cannot find. The center column is a Gravity Forms button.
