In this article I’ll show you how to fix the error “Updating Failed” in the WordPress page and post editor. In most cases this is a very simple fix.

The Why

This error has become quite common with the recent release of WordPress 5.0 which included the new Gutenberg editor.

The WordPress support team at WP Mantis has probably resolved this issue 10 times in the last 5 days.

So far in all cases this issue was caused by a conflict in the new WP Gutenberg editor and a 3rd party page builder.

Because this was so common, we did some independent testing. And so far the only page builder we have not seen this issue with is Elementor.

These page builders have had the issue:

  • WP Bakery
  • Beaver Builder
  • Divi

How To Fix It

As mentioned, this is a simple fix in most cases.

All you have to do is deactivate the Gutenberg editor to resolve the conflict and allow your page builder to function as it should.

How to disable Gutenberg:

  1. Install the Classic Editor plugin
  2. Activate the Plugin
  3. Done!

Here is a quick video to show these steps:

If This Doesn’t Work

First thing will be to do the typical WordPress troubleshooting, deactivate all plugins, test, then reactivate one at a time.

You can also try activating debug mode to see if that helps you identify the cause. Here is a quick video to show you how to do that. Note this does require FTP access.

define('WP_DEBUG', true);

To turn off debug you can remove the code or simply change “true” to “false”

define('WP_DEBUG', false);

    • Well Ron, this is a solution! However, if you would like one that doesn’t require the use of the Classic Editor plugin you should contact your theme/plugin provider for whichever page builder solution you use and ask if they have a more permanent solution.

      Be sure to let them know that you don’t want a “lousy work-round” since they are likely to suggest activating the Classic Editor plugin.

      Please don’t use the comments of this blog again and please avoid coming here if you want to be a jerk!

  1. The problem is with the Permalink, Changing the permalink is fixing the issue. (I think that is what Heather was talking about in the previous comment)

    But not for me, since the permalink that is causing the problem is the one I need to have. And I need to have the new editor, not the old one so I am back to square one.

  2. Thanks Chris for the insight

    Your info led me to find a plugin “Disable Gutenberg” and installed it. This removed all the Gutenberg stuff. Worked for me, but lost the additional tools Gutenberg provides. I reactivated Gutenberg and the problem came back so I disabled it completely for now until WordPress fixes the problem


  3. In my case, enabling the Apache2 rewrite module fixed the problem, allowing me to continue using the block editor and post name style permalinks.
