Parallax background not working with pagebuilder

Hi,

Regarding this post : https://siteorigin.com/thread/how-to-add-parallax-scrolling-to-a-page-builder-row/

I followed all instructions but it doesn’t work. The problem is that I have an existing page where all pagebuilder elements are active (rows, slider, and some custom html placed in text widgets) I need all that content to copy in the parallax item, but I cannot copy that content to a parallax item.

When I try to get that content in html code by clicking “revert to editor” the whole page elements are gone and the page is a mess.

How can I get that existing content so I can paste it in the parallax item?

THanks in advance!:-)
