How to fix the Gutenberg ‘Updating failed’ problem.

WordPress is a wonderful opensource project. But now and again it throws up strange oddities and errors that will prevent an easy workflow.

Recently, after spending an age restyling and modernising a very old WordPress blog, I ran into one of these strange oddities. The newly updated blog wouldn’t save or preview new posts.

What was the point of making the old blog pretty when I wasn’t able to publish new posts? Search after search revealed the same problem was bogging down many others. Gutenberg, the new post editor in WordPress seemed to have been at the root of the problem, or so it seemed.

After spending many hours trying to work through the, ‘Updating failed’ issue it was time to get to bed. I closed the laptop and decided to battle another day.

You can accomplish anything after a good nights rest

The following afternoon I opened up the laptop again. Determined to find a solution to this Gutenberg thing. Why was it preventing me from saving a new post or from previewing the new post in WordPress?

Then I remembered having another unused blog already set up right here on Boardtalk.org. As both sites were on the same shared server, I would be able to see if it was the server setting causing the issue.

Some more experienced WordPress developers referred to the server settings as being the cause. And at this point, I had tried every other solution out there.

The Boardtalk.org WordPress blog was a clean, virgin installation. With no re-rights on the htaccess, no plugins and no custom theme – just what came out of the box.

Who knew the answer was this simple.

Success, writing a blog post caused no problems. I could write, save and even preview without any issue. So it wasn’t the server settings.

Then I remembered my old go-to fixer when it came to those strange oddities in WordPress that nothing else fixed. Here’s how that went…

First, I went back to the WordPress blog that couldn’t save or preview new posts using the new Gutenberg posts editor. I always use Google Chrome but this time, believe it or not, I opened Internet Explorer.

Amazing, I could post, edit, save and preview new posts in Gutenberg using Internet Explorer without any problems.

The answer was simple, all I needed to do was to Clear browsing data in Google Chrome. Yep, that did the trick! No more ‘Updating failed’ when saving new posts in WordPress 5.

Who would have believed it was that simple to fix the Gutenberg ‘Updating failed’ problem… Clear Google Chrome Browsing Data!
