How to Disable Gutenberg without a Plugin


Most people use the plugin ‘Classic Editor’ to disable Gutenberg, but did you know that it is actually really simple to do this with code? With over 5 millions installs, it’s quite clear that a lot of people go for the simple option.

The code needed to disable it is actually very short and simple, so there is no need for a plugin to do the job, just add the following snippet in your theme’s functions.php file:

    add_filter( 'use_block_editor_for_post', '__return_false' );

Yup, it’s that simple… just one line of code!

There are cases where you may want to enable Gutenberg only in some condition. Below are some frequently used examples:

Allow Gutenberg for Posts Only

We use the same filter and return true if itโ€™s on post edit page.

add_filter( 'use_block_editor_for_post', 'my_disable_gutenberg', 10, 2 );

function my_disable_gutenberg( $can_edit, $post ) {
  if( $post->post_type == 'post' ) {
    return true;

  return false;

Allow for Page with the Template “Allow Gutenberg”

First, create a new Page Template, take note of the file name:

 * Template Name: Allow Gutenberg

require_once 'page.php';

Then, still using the same filter, add a conditional to check if it’s using that page template:

add_filter( 'use_block_editor_for_post', 'my_disable_gutenberg', 10, 2 );

function my_disable_gutenberg( $can_edit, $post ) {
  if( $post->post_type == 'page' &&
    get_page_template_slug( $post->ID ) == 'page-gutenberg.php' ) {
    return true;

  return false;


There are many reasons to disable Gutenberg on your WordPress site. Maybe you already use another Page Builder or it simply lacks the control ACF provides?

For old sites, you generally want to fully disable it. But you might want to have a little taste of Gutenberg by enabling it on Blog Post only. You can do so by following the code above. ๐Ÿ™‚

Hope that helps!
