I recently updated X & cornerstone and am now getting an http/https mismatch with the preview.
I host with WP Engine and have everything serving via HTTPS.
This is a mulltisite install, and so I don’t have anything in my “Settings -> General” section signifying https vs http.
In my multisite admin, the Site Address (url) is https:// and my siteurl is https://
In my wp-config.php file both WP_HOME and WP_SITEURL are set to https://
My permalinks are all showing as https://
And I am still getting the error:
The preview could not load due to a http/https mismatch. Please check that HTTPS is properly configured on your site.
