Upfront Editor Issues: Background Image, Menu, Buttons, Preview

I am not able to:
- See the background image I added to the theme (Preview is just a white background, I see it in the editor though)
- See the navigation menu (It is in the top right corner of the site but invisible, in Preview and editor)
- I can't edit button text, I double click, single click, etc. (It just tries to take me away from the page)
There seems to be other errors with editing elements and previewing as well. I'm using Google Chrome...
I've granted support access via the dashboard so you can have a look.
