How to Disable the WordPress Block Editor (Gutenberg)

Different Ways to Disable the Block Editor

Method 1: Using a Plugin (Recommended for Most Users)

The simplest and safest way to disable Gutenberg is by installing the Classic Editor plugin.

Classic Editor Plugin

• Official WordPress plugin
• Over 5 million active installations
• Maintained by WordPress contributors
• Download Classic Editor

After installation:

1. Go to Settings > Writing
2. Choose your preferred editor settings
3. Save changes

Method 2: Using Code (For Developers)

Add this code to your theme's functions.php or custom plugin:

Completely disable the block editor for all post types:

add_filter('use_block_editor_for_post', '__return_false');

Disable block editor for specific post types:

function disable_gutenberg_for_specific_posts($use_block_editor, $post_type) {
    // Add post types where you want to disable Gutenberg
    $disabled_post_types = array('post', 'page');
    
    if (in_array($post_type, $disabled_post_types)) {
        return false;
    }
    return $use_block_editor;
}
add_filter('use_block_editor_for_post_type', 'disable_gutenberg_for_specific_posts', 10, 2);

Method 3: Using wp-config.php

Add this line to wp-config.php before the "happy blogging" line:

define('CLASSIC_EDITOR_REPLACE', true);

Best Practices & Security Considerations
