Main Menu not working upgrading from 2.4.5 to 2.7.1

Hi.
I upgraded to WP 3.9 and am having the issue I am reading about regarding not seeing the text in the Layout Builder text editor. So I decided to update the theme and am running into some serious issues with the layout changing. The big thing is my main menu (logo left, menu right) is broken. I try to change its orientation to be bottom, etc to try and reset it or something but no luck. I have a child theme and some custom css, but even when I turn off my custom styles it is doing the same thing. The site is in staging so I will have to post a private reply to give you the info to take a look and see exactly what I am talking about. Do you want an admin login and ftp?

Thank you.
