    When trying to update a post or page on local dev site i keep getting this error “Updating failed. Error message: The response is not a valid JSON response.”

    Doesn’t happen on live site.

    I have run Health Check & Troubleshooting mode but still get the error so it’s not a theme or plugin issue.

    I DON’T get the error when running the Classic Editor plugin. I prefer the new block editor so would like to fix this issue than rather just avoid it.

    Any help/tips would be greatly appreciated.

    Many thanks,

    The page I need help with: [log in to see the link]

    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, permalinks may need resetting, etc.
