Trying to use foo gallery and foobox to work around the current lightbox issues Cornerstone seems to be having.
I’m using the Single Thumbnail Gallery option that let’s me place a single image on the page and when you click on it foobox displays a set of images.
The problem is that it doesn’t display on the builder. It does display and function on the site page properly, but I can’t see it in the builder, which make layout difficult.
It uses a shortcode placed in a text box [foogallery id=“2585”]. But this may be similar to the issues you are having with shortcodes currently.
All other image plugins have been turned off.
