I just upgraded to Cornerstone 5.0.11 and I’m having some problems.
The first problem occurs when I create a new section and select a layout. I’m selecting a single-column layout
But the column only occupies a thin sliver on the left.

Next, if I drag a Video object onto it the column disappears:

The column, with video, do still exist. I can see them in Outline view:

But the video object remains invisible in the page layout—even if I add video embed code.
This was working fine earlier this morning before I upgraded. Is there a fix for this?
