Was testing the new GP Premium version 1.11.1 update and the new external CSS file.
It doesn’t seem to be including the style.min.css when you are in a preview in the editor. This basically makes all the previews lose their styles.
I did a quick test and just dropped /wp-content/uploads/generatepress/style.min.css into the header of my test site and then the preview worked fine.
But if you compare a blog post with what is loaded in the editor during a preview you’ll see this file is for some reason missing.
Happy to provide any other information if you need it. I was able to replicate this on a couple of sites.
That’s what I thought but it doesn’t seem to be happening. My test site is at Kinsta, I disabled every plugin except for the latest GP Premium and still the same issue. I’ve cleared the entire site cache, disabled CDN, etc. The site is running on latest WP version.
