Not exactly. I know the wp-views shortcode has an issue. If you log into the site, navigate to the preview page that I've entered into the secure note.
The page looks fine on the front-end (what the website visitor would see).
It's on the back end that the page is blank. If you edit the page with Cornerstone, the entire content area (its using content with right sidebar) is blank.
If you enter the skeleton mode, you will see that it has classic section, classic row and classic columns.
If you click on one of the classic text element, it will show you the text that is properly rendered on the front-end.
What I don't understand is why none of the sections, rows, columns and elements show up in the page builder mode.
