Hi,
Sometimes when I make a change in Cornerstone on my production sites, I suddenly get a mixed content error. Then I discover that this is because the URLs have suddenly changed from the production domain to the dev domain:

This makes 0 sense. They weren’t originally uploaded there and I have never copied a database up to production from dev before. This has happened multiple times on two sites with X and Cornerstone installed, so I wonder if it’s causing it somehow. I was just looking at my home page and making revisions multiple times when a mixed content warning suddenly appeared, and when I inspected, sure enough, some image URLs were all of a sudden showing as being served from dev.
I have verified that my wp-config.php file does not contain dev site DB credentials and my base URL in Settings is not set to the dev site.
Any idea what’s happening here?
