I apologize. I am building a site using Theme Test Drive, so I can’t actually link to the site.
I’ve been building a site using the Page Builder. I got to my 10th section/row. I added the row, a text widget, and a background image and it was fine. Then I added my html, updated the page, and it switched to the editor view. When I switch back to the page builder, everything is gone. I rebuilt my site twice and had the same issue in the same area. Here is the jsfiddle for the code I add before it breaks. Nothing really out of the ordinary. Am I missing something? Is there some kind of maximum amount of content allowed? I have no idea why it would just glitch and disappear.
