The easiest way to disable Gutenberg is to install my free plugin, Disable Gutenberg. It is a simple plugin focused on one thing: disabling Gutenberg and restoring the default classic WP Editor screen. Just enable the plugin, choose your options and done. Options include:
- Disable Gutenberg completely (all post types)
- Disable Gutenberg only on specific post types
- Disable Gutenberg for specific user roles
- Disable Gutenberg for any theme templates
- Option to hide the “Try Gutenberg callout nag
- Option to hide the Gutenberg menu item
So it’s flexible yet simple, and super easy to use.
