in my case your trick not work sir i make slider plugin but still
error is :- Updating failed. The response is not a valid JSON response.

Can you make a video about the best practices to build plugins, like separate HTML from PHP code...

I'm getting the same message - Publishing failed. The response is not a valid JSON response. - when trying to simply publish pages.

Thank you so much for this. 7 minutes that will save lots of people weeks of frustrating searching! I'd run into that same problem recently, and gave up looking for a solution after a while.

Hi! I have a different problem, I can publish but the error occurs when I wanna add the picture. How I can fix that? I would appreciate your recommendations. - for image: The response is not a valid JSON response.

How to solve this problem

Hi Joshua, I have many plugins and I don't know what plugin causes this error. Do you have any solution to this? All my plugins I need them and i want to keep them as it is. But I want to be able to update my pages at the same time as well. Thank you for your time.

So, basically, Gutenberg SUCKS. What else is new in 2020 :/

I'm returing some html through my shortcode but it is not working at all tried everything but no luck. It's showing update failed but in front end its updating the content.

hi, how to resolve this while still echoing?

Thank you so much .

I apologize that the camera goes in and out of focus.. Wrong focus option selected. I hope this video helps some that receive this error or wonder why we return the content instead of escaping php and writing it as HTML.
