I am working on the innersport.com site with the air theme, and if I make any additions to any pages, whether through the classic editor or the page builder, the page’s contents disappear.

I tried installing a centered image in one case through the classic editor, (On the main static page,) and then I tried inserting a Facebook icon to the right side of the page through the page builder. (On a sub page with patient form links.) In both cases the header content remained but the main page content just uped and poof! disappeared. What is going on?
