Error - The preview could not load due to the iframe response being incomplete

Since upgrading to the latest version of Cornerstone we get the following message when trying to edit a page :

Any guidance on how it can be resolved?

Hi @scope,

Thanks for reaching out.

There could be a plugin or custom code that affects the preview of the builder.

I recommend the following troubleshooting procedures before we investigate the settings.

  1. TESTING FOR THEME RELATED ISSUE
  2. TESTING FOR PLUGIN CONFLICT
  3. THEME UPDATE
  4. CHILD THEME
  5. CSS/JS CUSTOMIZATION
  6. VERSION COMPATIBILITY

Only if none of that helps, please give us the following information in a Secure Note.

  • WordPress Login URL
  • Admin level username and password

You can find the Secure Note button at the bottom of your posts.

Thank you.
