The preview could not load due to the iframe response being incomplete...?!

[Kobber]

Hi,

I can’t edit my posts layout in the layout builder.

I got the: “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.”

At first I thought it was a plugin conflict, but no. After that I changed the wp-config debug mode from false to true, but no luck either.

Then I remembered that I recently changed my permanent links regarding my blog post links from: vektropol(.)dk/this-is-a-blog-post/ to: vektropol(.)dk/blog/this-is-a-blog-post/ - and I think that it is what’s causing the error.

Can I do something about that, or do I have to create af new layout?

Hi @Kobber,

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

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.

Cheers!
