Sorry to hear about the trouble! An "Updating failed" error can be caused by something local to your web server blocking your site's API or it can be caused by an incompatible server configuration or a plugin conflict.

First, check to make sure your site's API is working properly. You can do that by adding wp-json to the end of your site URL—if you get back an error, you will need to investigate why the API is not working for your site. Otherwise, you should just see a whole lot of text.

Next, check the console panel in your browser's web development tools at the time you see the "Updating failed" error appear. Sometimes an error will appear there that can help pinpoint the problem. If you spot an error, copy it into a reply here or take a screenshot and drop it into a reply.

I have a similar issue. Neither Auto-Save or Publish work. I get "Updating failed" and "Publishing failed." I also cannot preview Gutenberg created posts/pages. I get the logo animation, but nothing loads.

Adding wp-json works correctly. Here are the console messages when on the page:

When I hit Publish, I get a duplicate "[object Object]" message.

Thank you for any help you can provide!

Update: adding wp-json to the end of the URL works, but when I add a trailing slash, I receive a 500 error.

Go to: /wp-json

If giving error, go to permalinks and click save
wp-admin/options-permalink.php

Test /wp-json again
