Preview could not load due to the iframe response being incomplete

When attempting to use Cornerstone to edit a page new or existing I get an error:
The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.

Hi there,

Thanks for writing around! Can you please follow this guide first https://theme.co/apex/forum/t/troubleshooting-builder-preview-warnings/14404

Let us know if it still doesn’t work!

Sorry, I should have more explicitly stated that I’ve already been through that document with no luck.

Hello @Lassiter,

Thanks for updating the thread. :slight_smile:

In that case please share login details (username/password) in a secure note for us to take a closer look.

Thanks.

I’ve been working with support at Bluehost, as I’d found another problem that lead me to think there was a misconfiguration on their side. Turns out I was correct.

My problem is now a non problem.

Thanks,
Paul

Glad to hear that the issue is resolved now. :slight_smile:
