The preview could not load due to the iframe response v7.2.3

I was building a page on v7.2.3 using the Ethos photography template and it was working as it should. And now this error came up. I didn’t change anything on my server.

How do I fix this?

These are the only plugins im using

Hello @Avantscape,

Thanks for writing to us.

It might be the issue of plugin conflict, version compatibility issue or permalink issue. I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

  1. Testing for Plugin Conflict
  2. CSS/JS Customization
  3. Version Compatibility
  4. Disabling Cache
  5. Child Theme

If none of those work, It would be best if you could copying your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details

  • WordPress Login URL
  • Admin level username and password

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


I am having the exact issue? We you able to narrowing down the problem? I have gone through the suggested troubleshooting techniques. This just starting happening with the new version of X & Cornerstone.

For what it is worth I was able to resolve my issue. It appears that I didn’t have the new version of X installed like I thought I did. I was still running version 7.2.3. Updating to version 8.0.11 fixed my similar issue. I hope this helps!
