Are you unable to find the ‘Custom Fields’ option on your WordPress site?

‘Custom fields’ is an advanced WordPress feature that helps you add custom content and metadata to your WordPress posts and pages.

In this article, we will show you how to quickly fix the custom fields not showing issue in WordPress.

Fixing Custom Fields Not Showing Issue in WordPress

Custom fields are typically associated with WordPress posts, pages, or custom post types.

Often, you will find custom fields mentioned in various WordPress tutorials around the web. Still, you will likely not see the custom fields option on your site, especially if you recently started your WordPress blog.

In the past, custom fields were visible by default on the post-editing screen of all WordPress sites.

However, the WordPress core development team decided to hide it by default for all new users since it is an advanced feature.

They also made it easy for anyone to make the custom fields visible with just a few clicks from within the post editor.

Simply create or edit an existing post/page, then click on the three-dot menu in the top right corner of the screen.

Block editor preferences

At the bottom of the menu, click on the ‘Preferences’ option.

This will bring up the block editor ‘Preferences’ popup. From here, you need to switch to the ‘Panels’ tab and switch the toggle next to the ‘Custom Fields’ option.

Show custom fields

Note: If you don’t see the Custom Fields option on your site, then please scroll to the troubleshooting section below in this article.

WordPress will then tell you that a page reload is required to enable Custom Fields.

Simply click on the ‘Enable & Reload’ button to continue.

The editor screen will then reload, after which you can scroll down to the bottom of the page and find the ‘Custom Fields’ box there.

WordPress remembers your display choice and will continue to display the custom fields box whenever you edit posts or pages on your WordPress website.

You can now use the Custom Fields box to add, edit, and delete custom fields and their values.

What Are Custom Fields? What Can You Do With Them?

By default, when you write a new post, page, or any content type, WordPress saves it into two different areas. The first part is the body of your content that you add using the block editor.

The second part is the information about that particular content. For example, title, author name, date/time, and more. This post information is called metadata.

Apart from the default post metadata, WordPress also allows you to save custom metadata by using custom fields.

To learn more, see our beginner’s guide to WordPress custom fields with examples, tips, and tricks you can use on your website.

WordPress developers use custom fields to store custom post metadata for your posts. For example, the All in One SEO plugin uses custom fields to store SEO settings for your posts.

However, plugin developers usually create custom meta boxes instead of using the default custom fields box. This makes it easier for users to input information.

If you want to create a custom meta box to easily input custom metadata, then see our guide on adding custom meta boxes in WordPress.

Troubleshooting Custom Fields in WordPress

Recently, one of our readers encountered a problem where the Custom Fields option was missing from the block editor preferences. After some investigation, we found the cause of the issue.

If your WordPress site is missing the Custom Fields option under the ‘Preferences’ menu, then you need to check if you have the Advanced Custom Fields (ACF) plugin installed and activated on your website.

ACF is a popular WordPress plugin that developers use to create custom meta boxes.

ACF version 5.5.13 added a setting to remove the default WordPress custom field meta box. This speeds up the load times on the post-editing page. The idea is that you shouldn’t need the default meta box since you are using ACF.

However, if you want to enable the default WordPress custom field meta box, then you need to add the following code to your WordPress theme using the functions.php file or WPCode:

add_filter('acf/settings/remove_wp_meta_box', '__return_false');

For more details, please see our guide on how to easily add custom code in WordPress.

    If this is in additional section is it really worth it to put information there? Does this benefit SEO in any important way? Or is it more for us? I don’t really understand the benefit here.

    • WPBeginner Support says

      It would depend on what custom fields weren’t showing for you. Sometimes the section for a plugin would disappear and following this guide would have the section reappear for you.


  3. Keith Stanfield says

    Custom fields are not showing under product data with this plugin, I added the function code and enable the custom fields checkbox but nothing shows up.

    • WPBeginner Support says

      If you are using the block editor, we would recommend checking under preferences to ensure the custom fields are not hidden based on those settings. :)


  4. Dalia Sued says

    Custom fields disappear from WordPress 6.1, since the new WordPress update, all plugins that have custom fields have disappeared from all posts type, including posts and pages.

    • WPBeginner Support says

      Custom fields are still available, you may have them disabled in your editor. If you go to the top-right and click the three dots, then go to preferences you should find the option to enable custom fields.

    i have ACFs that dont display on my home page. i know the ACF pro plug in needs to be updated. Would this result in why my fields aren’t displaying on my homepage?

    • WPBeginner Support says

      That could be part of the issue. If you reach out to the plugin’s support they should be able to assist.


  6. Ushir Shah says

    Thank you! Adding the filter to the functions file because of ACF was my issue, what a great help!

  7. Cedric Shaw says

    So we have ACF running and have the “fix” in our functions.php file. The issue we are having is that the drop down field is only showing 148 entries and not displaying all of the custom fields. Is there something that is preventing them from not displaying all of the custom fields?

    • WPBeginner Support says

      For that, you would want to reach out to ACF’s support to see possible reasons for this issue.


  8. Poul says

    I spend a couple hours to solve this problem (find out why i don’t see that option in “Screen Options” menu).

    Thanks! :)

  9. Luke says


    Thanks for your tip.
    I’ve installed ACF, however still don’t see custom field checkbox.
    When I tried to paste the code I got following error message: syntax error, unexpected ‘add_filter’ (T_STRING)
    Could you please advise?

    Many Thanks!

    Hi. I have re-instated the custom fields. I can add new, but original fields are not showing in the back end (still displayed on website) so I cannot edit my content. Any ideas? Thanks

  11. Serge says

    Super. We were looking for the setting that was hiding the custom fields. We knew it was a setting but could find where. Thanks also for the bit of code, could come handy eventually.

  12. Dave Combs says

    Sadly, the add_filter code for the functions.php file did not work, so I’m off to find to try to solve the problem.

    • WPBeginner Support says

      Thank you for letting us know, we’ll certainly keep an eye out for other solutions to recommend.


  13. David says

    I lost a day of work trying to figure out why my custom metabox wasn’t showing. Then I checked the source code and it was there with the ‘hide’ class suffix. Thanks a lot ACF :(

    Thank you for the fix :)

  14. Robbie says

    Just wanted to say thanks for the add_filter() trick in the troubleshooting section. A new client needed me to fix something on a site I’d never seen and this was what I finally needed.

  15. Julia Moss says

    Thank you so much – this problem has been driving me mad! Your code for the functions file worked.
