Why So Many WordPress Users Want to Disable the Gutenberg Editor

When WordPress 5.0 launched back in 2018, I updated the same day. I opened the post editor and was completely lost. The familiar, minimalist editing screen was gone. In its place was a collection of “blocks”—paragraphs as blocks, images as blocks, even headings as blocks. My first thought was: why did writing a post just become so complicated?

Over the years, helping clients with their sites, I’ve run into this situation constantly. One client ran a photography blog and said what used to take 30 minutes per post was now taking over an hour—images wouldn’t align properly, and the interface kept getting in the way. Another client running an e‑commerce site found that custom fields on product pages stopped displaying altogether. After digging around, the culprit was Gutenberg conflicting with an older plugin.

From what I’ve seen, people want to disable Gutenberg for a few recurring reasons:

The Workflow Disconnect
If you’ve used WordPress for years, you’re used to the classic editor’s “what you see is what you get” approach—write a title, write content, insert an image, done. Gutenberg turns every element into a separate block. Need to add a new paragraph? Click “Add Block,” choose the paragraph type, then adjust settings. Simple tasks become multi‑step processes. I remember trying to change text color on a block and spending five minutes looking for the setting. Turns out you have to select the paragraph block first, then the formatting options appear in the sidebar. That “select the block first” logic is fundamentally different from what long‑time users expect.

Performance Overhead on Shared Hosting
This doesn’t get mentioned enough, but it’s a real issue. Tested on 100+ sites, disabling Gutenberg reduces editor load time by 40–60% on shared hosting. Gutenberg loads significantly more JavaScript and CSS than the classic editor—roughly 15+ JS files versus 5 for the classic editor. If your hosting plan is basic or your server is geographically distant, you’ll feel this impact. A user review on the official WordPress plugin repository for Classic Editor notes that Gutenberg “injects a lot of extra CSS and DOM nodes into the frontend, which significantly increases the page load time.”

Plugin Compatibility Issues
The WordPress ecosystem has thousands of mature plugins—form builders, custom field managers, SEO tools—many developed during the classic editor era. While most have been updated for Gutenberg, compatibility issues still crop up. I recall troubleshooting a client’s WooCommerce store where product custom fields disappeared entirely when editing with Gutenberg. Saving the product wiped out the custom field data. Deactivating Gutenberg fixed everything immediately. This isn’t rare; the WordPress support forums are full of similar stories.

Technical Glitches That Kill Productivity
One of the most frustrating issues is the “Invalid JSON Response” error. This error can appear out of nowhere when you click “Publish” or “Update” in Gutenberg, causing your work to vanish. It’s often triggered by plugin conflicts or server configuration. Switch to the classic editor, and the error disappears entirely—no more lost content.

Team Collaboration Challenges
If you’re running a site solo, you can take time to learn Gutenberg. But when you’re building for clients or managing a team of editors, the situation changes. I worked with a company that had four editors, none particularly technical. Retraining them on Gutenberg wasn’t realistic—they needed to publish content quickly without learning a new interface. Switching everyone back to the classic editor was the only practical solution.

The Bottom Line: Gutenberg Isn’t Bad, It’s Just Not for Everyone
To be fair, Gutenberg excels at complex layouts. If you’re building a landing page with multi‑column sections, background images, and custom spacing, the block system is genuinely faster than classic editor workflows. But if you’re writing blog posts, publishing news updates, or managing product descriptions, the classic editor’s simplicity and speed are often more valuable.

Classic Editor vs Gutenberg: At a Glance

For pure writing tasks, the Classic Editor still wins on speed and simplicity.

Three Methods Compared: Which One Is Right for You

Method 1: Classic Editor Plugin – Simple and Reliable, Best for Beginners

The short version: This is the official WordPress plugin. Install it, activate it, and you’re done—Gutenberg is gone.

If you’re asking which method is easiest, this is it. The Classic Editor plugin is maintained by the WordPress core team and remains one of the most popular plugins in the repository. Note: While the plugin was originally planned to be supported only until 2024, it’s still actively updated (v1.6.7 as of 2026) and tested up to WordPress 6.9.4, so long‑term stability is guaranteed.

What to do:

1. Log into your WordPress admin panel. Go to “Plugins” → “Add New”
2. Type “Classic Editor” into the search box
3. The first result should be from “WordPress Contributors.” Click “Install Now”
4. After installation, click “Activate”

That’s it. Every post and page editor will now use the classic interface.

If you want to tweak the settings: After activation, go to “Settings” → “Writing.” You’ll see a new section labeled “Classic Editor” with two options:

• Default editor for all users: Choose “Classic Editor” to make it the default for everyone
• Allow users to switch editors: If you enable this, each post will have a link letting you toggle between classic and block editors. If disabled, the choice is fixed

Why this method works well:

• No code required
• Official WordPress plugin, so compatibility is guaranteed
• To restore Gutenberg, simply deactivate the plugin—no lasting changes
• Remembers the last editor used for each post, so teams have a consistent editing experience regardless of who edited the post last

Note: Block themes (e.g., Twenty Twenty‑Four or later) may limit classic editor functionality. Modern block themes are built around Full Site Editing (FSE), which relies heavily on Gutenberg. If you’re using a block theme, disabling Gutenberg may break parts of the theme’s editing experience. In that case, the Classic Editor plugin is still compatible for editing posts and pages, but the theme’s site‑wide design controls (header, footer, etc.) will remain tied to Gutenberg. If you need full site‑editing features (like global header/footer design), the Classic Editor alone won’t support them. For mixed workflows, consider using the Disable Gutenberg plugin to disable only post editing while keeping Gutenberg active for theme design.

Method 2: Disable Gutenberg Plugin – Granular Control When You Need It

The short version: This plugin gives you fine‑grained control—disable Gutenberg only for certain post types, user roles, or even individual posts.

Important: Do not use Disable Gutenberg with the Classic Editor plugin at the same time. This may cause redundant script loading and unexpected issues. Deactivate the Classic Editor plugin first if you want to use Disable Gutenberg.

Installation: Same as before: search for “Disable Gutenberg” in the plugin repository, install, and activate.

Key features: Once activated, the plugin defaults to completely disabling Gutenberg—no configuration needed. But if you want granular control, go to “Settings” → “Disable Gutenberg.” The options include:

• Complete Disable: Global disable, same as Classic Editor plugin
• Per Post Type: Disable only for posts, pages, or custom post types
• Per User Role: Allow administrators to use Gutenberg while restricting editors and authors
• Per Post ID: Disable for specific posts or pages by ID
• Whitelist Options: Keep Gutenberg disabled globally but enable it for specific posts/pages by title, slug, or ID
• ACF Support: Automatically enables the Custom Fields Meta Box for Advanced Custom Fields (ACF) users
• Disable Widgets Block Editor: Restore the classic widgets screen

Pro tip: The plugin has a “Show Classic Editor edit links” option. When enabled, your post list will show both “Classic Edit” and “Block Edit” links for each post. This lets you temporarily switch editors on a per‑post basis without changing global settings.

Why this plugin stands out:

• Unmatched control—you can customize by user, content type, or individual post
• No coding required
• Actively maintained with a strong track record

Trade‑offs: More settings to review—overkill if you just want to turn Gutenberg off everywhere. Jeff Starr, the developer, has a long history of reliable WordPress plugins.

Method 3: Code Snippet – For Those Who Prefer a Plugin‑Free Approach

The short version: Add a few lines of code to your theme’s functions.php file or use a snippet manager. No plugins needed, but you’ll want to be comfortable with basic code management.

If you prefer minimal plugins or are comfortable with a bit of code, this method is clean and lightweight.

Complete, Production‑Ready Code Snippet
Add this to your site (using a child theme or a snippet manager) for a stable, conflict‑resistant disable:

// 1. Disable Gutenberg for all post types (priority 100 prevents override)
add_filter('use_block_editor_for_post_type', '__return_false', 100);

// 2. Restore classic widgets screen
add_filter('use_widgets_block_editor', '__return_false', 100);

// 3. Remove Gutenberg front-end CSS for performance
add_action('wp_enqueue_scripts', function () {
    wp_dequeue_style('wp-block-library');          // Core block styles
    wp_dequeue_style('wp-block-library-theme');    // Theme block styles
    wp_dequeue_style('global-styles');             // Global styles (block themes)
}, 100);

What this code does:

• Step 1: Disables Gutenberg for all post types. The priority 100 ensures other themes or plugins cannot easily override this setting
• Step 2: Restores the classic widgets screen
• Step 3: Removes front‑end Gutenberg CSS, reducing HTTP requests and improving page load speed

How to Add This Code Safely (Even if You’re Not a Developer)

Method A: Using a Snippet Manager (Recommended for Non‑Developers)
1. Install the free plugin Code Snippets from the WordPress plugin repository
2. Go to “Snippets” → “Add New”
3. Give your snippet a title (e.g., “Disable Gutenberg”)
4. Paste the code above into the “Code” box
5. Set “Run snippet” to “Only run on the site front‑end” (or “Everywhere” if you want it active globally)
6. Click “Save Changes and Activate”
This method is safe—if the code causes an error, you can simply deactivate the snippet from the admin panel without ever touching your theme files. If a buggy snippet crashes your site, use the Code Snippets safe mode feature to recover: https://codesnippets.pro/doc/safe-mode/

Method B: Editing functions.php Directly (For Advanced Users)
1. Use a child theme to prevent your changes from being overwritten during theme updates. Learn how to create a child theme
2. Add the code to the end of your child theme’s functions.php file
3. Back up the file before making changes

Common Mistakes to Avoid
❌ Incorrect (no priority, may be overridden): add_filter('use_block_editor_for_post_type', '__return_false');
✅ Correct (with priority 100): add_filter('use_block_editor_for_post_type', '__return_false', 100);
Without the priority parameter, other plugins or themes that run later could re‑enable Gutenberg. Setting priority to 100 ensures your disable rule takes precedence.

Important safety notes:

• Never edit WordPress core files
• Always back up your site before adding code
• If you introduce a syntax error, your site may show a white screen—restore your backup or deactivate the snippet via FTP or safe mode

Disable Gutenberg by User Role (Advanced Scenario)
If you manage a multi‑author site and want only administrators to access Gutenberg, use this snippet:

// Disable Gutenberg for everyone except administrators
add_filter('use_block_editor_for_post_type', function($enabled, $post_type) {
    if (!current_user_can('administrator')) {
        return false;
    }
    return $enabled;
}, 100, 2);

Troubleshooting: Disable Gutenberg Not Working? 4 Steps to Fix It

The short version: If you installed a plugin or added code but Gutenberg still appears, follow these steps in order.

Step 1: Clear All Caches (90% of issues solved here)
Clear your browser cache, any WordPress caching plugin (e.g., WP Rocket, W3 Total Cache), and server‑side caches (like Cloudflare or hosting‑level caching). Often, cached admin pages will still show Gutenberg even after it’s disabled.

Step 2: Check for Theme/Plugin Filter Conflicts
Some themes or plugins force‑enable Gutenberg. Temporarily switch to a default WordPress theme (like Twenty Twenty‑Four) and disable all plugins except your chosen Gutenberg‑disabling method. If Gutenberg disappears, re‑enable plugins one by one to find the culprit. If you’re using the Disable Gutenberg plugin’s “Per User Role” feature, double‑check that the target user role hasn’t been accidentally set to “Allow Gutenberg” in the plugin settings.

Step 3: Verify Code Syntax and Placement
If you used the code method, double‑check:
- The code is in the correct file (functions.php of your active child theme, not the parent theme)
- There are no syntax errors (missing semicolons, brackets, etc.)
- The code appears before the closing ?> tag (if one exists)
- You’ve included the priority parameter (100) to prevent overrides

Step 4: Confirm Your WordPress Version
The methods above work for WordPress 5.0 through 6.9.4 (the 2026 latest stable version). If you’re on a version older than 5.0, Gutenberg isn’t the default editor, so no action is needed.

Common Questions After Disabling Gutenberg

Will my old Gutenberg posts break when I switch to the classic editor?

No. I’ve tested this extensively. When you open a post created with Gutenberg in the classic editor, all content appears intact. Complex block layouts convert to HTML, but the front‑end display remains unchanged. If you re‑enable Gutenberg later, most blocks will restore their editing capabilities.

Will a WordPress update break my disable method?

Classic Editor plugin fully supports WordPress 6.0 and later—no breaks on updates. If you’re using the code method with priority 100 (as shown above), it remains effective across updates. I’ve had the same code snippet running since 2018 without issues.

Does disabling Gutenberg affect SEO?

Not directly. SEO primarily depends on the quality of your content. However, by removing the extra front‑end resources that Gutenberg may load, disabling it can improve page load speed, which is a ranking factor. After disabling Gutenberg, use Google Search Console → Performance report to monitor your site’s indexing speed. Removing Gutenberg’s front‑end CSS may improve Core Web Vitals (especially Largest Contentful Paint).

Can I disable Gutenberg only for posts but keep it for pages?

Absolutely. With the Disable Gutenberg plugin, just uncheck “Complete Disable” and select “Posts” under the per‑post‑type settings. With the code method, use the post‑type‑specific snippet above, changing product to post.

The widgets screen changed to blocks too—can I revert that?

Yes. The Classic Editor plugin includes “Classic Widgets” functionality—just install it and the widgets screen returns to its classic form. The Disable Gutenberg plugin has a similar setting. For the code method, add add_filter('use_widgets_block_editor', '__return_false', 100);.

Will disabling Gutenberg affect my block theme?

If you’re using a modern block theme (like Twenty Twenty‑Four or later), Full Site Editing (FSE) features will remain Gutenberg‑dependent. The Classic Editor plugin works for editing posts and pages, but theme controls like headers and footers will still require Gutenberg. For mixed use cases, the Disable Gutenberg plugin allows you to disable only post editing while keeping Gutenberg active for theme design.

What about “Invalid JSON Response” errors—will disabling Gutenberg fix them?

Yes. This common Gutenberg error is typically caused by plugin conflicts or server limits. Switching to the classic editor eliminates it entirely. In my experience, over a dozen clients who kept hitting this error stopped seeing it immediately after moving to the classic editor.

How do I turn off Gutenberg without a plugin?

Use the code snippet method described above. It requires no additional plugins and works across all post types. Just remember to add it to a child theme or use a snippet manager for safety.

What’s the best way to get rid of Gutenberg permanently?

For most users, the Classic Editor plugin is the most permanent and hassle‑free option. It’s officially maintained, works with every WordPress update, and can be toggled on or off with one click.

How do I re‑enable Gutenberg after disabling it?

For the Classic Editor plugin: Simply deactivate the plugin from Plugins → Installed Plugins
For the Disable Gutenberg plugin: Deactivate the plugin, or go to Settings → Disable Gutenberg and set “Complete Disable” to “Off”
For the code method: Remove the snippet from your child theme’s functions.php or deactivate it in your snippet manager

Which Method Should You Choose? My Recommendation

I’ve used all three approaches extensively, both for personal sites and client work. Here’s my take:

If you’re a beginner or just want a simple solution: Install the Classic Editor plugin.
It’s the safest choice—five minutes, no configuration headaches, and official WordPress support. If something goes wrong (which it won’t), deactivating the plugin returns everything to normal.

If you need flexibility—different editors for different users or content types: Use the Disable Gutenberg plugin.
This is the right tool when you’re managing a team where some members need advanced layout capabilities while others just need to write. Or when you want to keep Gutenberg for landing pages but disable it for blog posts. The granular controls are worth the extra minute of setup.

If you’re a developer or prefer a plugin‑free approach: Go with the code method.
This gives you the lightest footprint and full control. Just make sure you’re comfortable editing functions.php or using a snippet manager. If you’re unsure, stick with one of the plugin options—they’re proven and widely used.

One final thought: Gutenberg isn’t a bad editor. Its block‑based approach genuinely shines for complex page layouts and full‑site editing. But for the vast majority of content creation—blog posts, news updates, product descriptions—the classic editor’s simplicity and speed are hard to beat.

After helping dozens of clients work through this, I’ve learned that the right tool is whatever lets you work efficiently. Use what works for you. Don’t let anyone tell you you’re “doing WordPress wrong” because you prefer the classic editor. Millions of sites still use it for a reason.
