    When I try to create a new post or update an old post, it doesn’t allow me to do so. Doesn’t allow me to save the draft also. it gives the following error

    ‘Publishing failed. The response is not a valid JSON response.’

    When I click back to the posts menu, it shows the page I just edited as ‘Auto Draft’.
    This problem goes away when I change the permalink structure from ‘post name’ to ‘plain’.
    However, I want to keep my permalink structure as a post name because it is better for the SEO.

    This error first came after I installed some new plugins. I tried deactivating them 1 by 1, still, the problem persists.
    I ran the ‘Plugin Detective – Troubleshooting’ plugin. It couldn’t find any errors either. The front end of the site works completely fine.

    “The response is not a valid JSON” It may be a lot of different things:
    – a plugin conflict either 1) a plugin doing something that creates output, thus breaking the response or 2) a plugin doing something with caching),
    – an overloaded server,
    – misconfigured http/https address in General Settings,
    – blocking rules on your server
    – permalinks may need resetting,
    – theme/plugin conflict,
    – check Site Health: From your WordPress dashboard, if you go to Tools and then select Site Health, then under the Status tab on that page, WordPress will show you any improvement recommendations that could help your website. An issue related to Rest API could also cause the JSON response error on your website. Moreover, if you find any issue there, solving the issue might also fix the JSON response error for your website, etc.

    Found the culprit plugin! It was an app expert, a PWA plugin. Had to give up the app in order to make the website work. I think it conflicts with Elementor or related plugins.
