I’ve now setup on a win10 laptop and problem is gone. I was using an xp laptop when problem suddenly appeared … I’ll just assume xp was the problem 🙂
Nastia and Jon,
I have the same problem. I have removed all other plugins as suggested Nastia and the problem persists. I am using the Twenty Seventeen theme with a child theme so that I can “Add a Custom Sidebar to Each Front Page Section and Page” as per the article “5 Excellent Ways to Hack the Twenty Seventeen WordPress Theme” by Jon Penland on Jan 03, 2017
Cheers.
