How to Redirect 404 Error and Not Found Pages in WordPress

---

To redirect all 404 errors to the home page in WordPress using the “.htaccess” file, you can use the following code:

---

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# Redirect all 404 errors to the home page
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . / [L]
</IfModule>

---

This code snippet will redirect any request that results in a 404 error to the root of your website, effectively directing users to the home page.

To implement this redirect, follow these steps:

1. Access your WordPress installation’s root directory.
2. Locate the “.htaccess” file and open it for editing.
3. Insert the code snippet provided above at the beginning of the file, before any other existing rules.
4. Save the changes to the “.htaccess” file.
5. Test the redirect by accessing a non-existent page on your website. It should automatically redirect to the home page.

Remember to exercise caution when modifying the “.htaccess” file, as incorrect changes can result in errors or disruptions to your website. Always keep a backup of the original file and consult with a developer or your hosting provider if you have any concerns.

Here’s an alternative method to redirect all 404 errors to the home page in WordPress, using PHP code instead of modifying the “.htaccess” file:

---

1. Open your theme’s “functions.php” file for editing. You can find this file in your WordPress theme’s directory (typically located at /wp-content/themes/your-theme-name/).
2. Add the following code snippet at the end of the “functions.php” file:

---

function redirect_404_to_home() {
    if (is_404()) {
        wp_redirect(home_url(), 301);
        exit();
    }
}
add_action('template_redirect', 'redirect_404_to_home');

---

3. Save the changes to the “functions.php” file.

This code creates a custom function called redirect_404_to_home that checks if the current page is a 404 error page using the is_404() function. If it is, it performs a redirect to the home URL using wp_redirect() and exits the script.

By using this method, you achieve the same result of redirecting all 404 errors to the home page. It provides an alternative approach when modifying the “.htaccess” file is not desired or accessible.

Remember to exercise caution when editing theme files and always keep a backup of the original file before making any changes.
