 - download wordpress from the official website
 - install it
 - go to wp-admin
 - go to Posts -> "Hello World" -> edit

 Already there are a bunch of errors in the console: (oh come on, I can't
 paste a screenshot!?!?)

 - edit the text and click on the "Update" button

 Expected: should work
 Observed: this error shows up at the top of the page:
 "Updating failed. The response is not a valid JSON response."

 and this can be seen in the console:
 ```
 api-fetch.min.js?ver=4c185334c5ec26e149cc:2
 POST https://*******.com/wp/index.php/wp-json/wp/v2/posts/1?_locale=user
 404 (Not Found)
 ```

 I didn't touch any settings, this is a fresh installation installed 10
 minutes ago.
