Hello Hannes,

Thanks for writing in!

The issue of the Cornerstone preview not loading when a YouTube embed is present is a known conflict. It’s almost always caused by a third-party plugin or an incorrectly formatted embed code.

Here is a step-by-step guide to troubleshoot and fix the problem.

  1. Deactivate all plugins to test for conflicts.

  2. Use the “Embedded Video” element with the full YouTube <iframe> code.

  3. Check the browser console for JavaScript errors.

  4. Update your theme, Cornerstone, and WordPress.

  5. Verify your Site URL settings for HTTPS mismatches.

  6. Test on a blank page to isolate the problem.

  7. Add cache exceptions for CDN services like Cloudflare.

Following these steps should resolve the preview issue. If the issue persists, kindly provide us with the URL of the page where you have inserted the Embed code.

Let me know how it goes.
