I had buttons that were working, displayed fine, no problem.
I updated the Cornerstone theme, and now the buttons don’t appear.
I have placeholders for the buttons in the Cornerstone builder (see image below), and the text and links are all there in the settings, but the builder preview doesnt show the button, only what you see in the screenshot, and online, no button shows up at all.
The same thing is also happening to my Quote element. My quote is typed up, settings are all in place, but in the builder, only the placeholder shows up, but online, there is no quote element.
