Cornerstone error The preview could not load due to the iframe

After update… If I edit a page with cornerstone, it open a screen that shows all the features and a big button of “START BUILDING”… after click it … " [Cornerstone issue “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.”]"

Any idea about a solution?

Hi Dario,

Thanks for reaching out.

Please update your theme because it fixes various conflicts with the theme options, a builder not loading, and plugin conflict. Pro to 4.0.8 or X to 8.0.8 and the cornerstone to 5.0.8. if the issue still persists after updating everything, please give us the following information in a Secure Note and also providing screenshot is a big help.

  • WordPress Login URL
  • Admin level username and password

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

Thank you.

Thank you so much!!! That fixed the problem.
