To date, try Gutenberg, preliminarily introduced in WP 4.9-beta3, in WP 4.9.5-beta1-42869, and WP 4.9.8-beta1-43502, respectively removed in WP 4.9-beta4, in WP 4.9-RC1, in WP 4.9-RC2, in WP 4.9-RC3, in WP 4.9.0, in WP 4.9.1, in WP 4.9.2, in WP 4.9.3, in WP 4.9.4, in WP 4.9.5-beta1-42883, in WP 4.9.5, in WP 4.9.6, in WP 4.9.7, and in WP 5.0-alpha, is embedded in core of WP 4.9.8 (2018-08-02) third quarter 2018 (The NeverEnding Story) according with this ticket.

How Work?

By default try Gutenberg is displayed only for users with administrator capability in WordPress 4.9.8 but when the Gutenberg plugin is installed and activated, is displayed for all user capability type.

An option configuration page is added to the settings -> writing menu so that you can set the callout display according to your needs. Stick to the screenshots for more details.

For now is not necessary also remove completely Gutenberg because it is not embedded on core of WordPress 4.9.8 but is only availabe as plugin. Ownever I’m working on future features of new configuration option settings to add this possibility.


A neat trick, is to put this single file dismiss-gutenberg-nag.php (not its parent directory) in the /wp-content/mu-plugins/ directory (create it if not exists) so you won’t even have to enable it, and will be loaded by default, also, since first step installation of WordPress setup!


This, is different from the other similar plugins, because uses the filter hook, and not the action hook. Filters should filter information, thus receiving information/data, applying the filter and returning information/data, and then used. However, filters are still action hooks. WordPress defines add_filter/remove_filter as “hooks a function to a specific filter action”, and add_action/remove_action as “hooks a function on to a specific action”.

What is Gutenberg?

Gutenberg is new block editor editing experience for WordPress 5.0+

About it

The code of this plugin, is not written with a php framework, but with a simple php editor, manually, compatible UTF-8 without BOM, and Unix LF. To avoid code corruption, do not edit it with WordPress embedded editor, or with any specifications incompatible editor.
