Updating failed. The response is not a valid JSON response

I was in the middle of creating a post, when I got the dreaded ‘Updating failed. The response is not a valid JSON response.’ I have tried disabling my plugins, but that didn’t work.

No problem. I downloaded the old wordpress post builder and it got rid of the JASON issue. I then tried uninstalling it, and it fixed the problem! No idea why.
