How to Fix WordPress Posts Returning 404 Error (Step by Step)

Have you ever tried to open one of your WordPress posts only to be greeted by a 404 error? At times, we experience that when we’re working on our own WordPress sites or helping our users

This error occurs when you can access your WordPress admin area and blog, but when you try to open a specific post, you’re met with a “404 Not Found” message.

It can be frustrating to see your content seemingly disappear, but we’ve found some workarounds to fix this issue. In this complete guide, we’ll show you how to fix WordPress posts returning 404 errors.

Why Are My WordPress Posts Returning a 404 Error?

There are several reasons why your posts might be showing a 404 “Page Not Found” error in WordPress. These can include:

• Plugin or theme conflicts: Sometimes, plugins or themes you’ve installed on your site can interfere with how WordPress handles permalinks. This can lead to broken links and 404 errors.
• Custom code issues: If you’ve added custom code to your website, there might be errors in the code that are affecting permalinks or causing other conflicts, resulting in 404 errors for your posts.
• Issues with your .htaccess file: The .htaccess file plays a role in how WordPress structures URLs. If this file is corrupted or missing, it can lead to 404 errors for your posts or pages.

How to Find All WordPress Posts With 404 Errors

Before we get to the solutions, it’d be good to figure out if this error is just happening to one or two posts or multiple posts. This way, you can determine the scope of the problem and choose the most appropriate solution.

One easy way to figure this out is to use Google Search Console. If you haven’t submitted your site to Google Search Console already, then read our guide on how to add your WordPress site to Google Search Console.

Once the Google bot has crawled and indexed your site, Google Search Console will then provide you with detailed information about your site’s performance, including any 404 errors it encounters.

To find out which posts are returning 404 errors, you can log in to the Search Console dashboard. Then, navigate to the ‘Pages’ report, and you will see a detailed list of all the errors.

For more information, you can read our list of tips for using Google Search Console to grow website traffic, which includes some tips on how to fix 404 errors with the tool.

That being said, let’s look at how to fix WordPress posts returning 404 errors. You can use the links below to jump straight to different solutions:

Method 1: Check for Plugin or Theme Conflicts and Custom Code Issues

Sometimes, plugins, themes, or custom code you’ve added to your WordPress website can interfere with permalinks or cause conflicts, leading to 404 errors. We’ve even experienced it ourselves when we’re testing tools on our demo site.

One way to solve this problem is to temporarily deactivate plugins. Plugins can sometimes disrupt how WordPress handles links.

Once you’ve deactivated the plugins, you can reactivate them one by one while checking if the 404 error reappears after activating each plugin. If the error shows up after activating a specific plugin, that might be the culprit.

You can then do a quick Google search for solutions related to that plugin or contact the plugin developer for support.

Similarly, your WordPress theme might be causing the conflict.

To check, you can temporarily switch to a default WordPress theme like Twenty Twenty-Three or Twenty Twenty-Four. All you need to do is go to Appearance » Themes and click ‘Activate’ on a default theme.

If the 404 error disappears with the default theme, it indicates a potential conflict with your current theme. You can then try troubleshooting the theme or consider using a different theme.

If you’ve recently inserted code snippets to your website, there might be errors in the code causing the 404 errors. Take a close look at the code you added and see if you can identify any mistakes.

The safest way to add code snippets to WordPress is with the WPCode plugin. This plugin lets you insert custom code without directly working with the theme files, reducing the risk of breaking your website.

Plus, whenever WPCode spots an error in your code, it will automatically deactivate the snippet and ask you to check it. You can also use the testing mode to check if your code works before pushing it to your live website.

If none of these solutions work, move on to the next method where we’ll troubleshoot your permalink settings.

Method 2: Fix Your Permalink Settings

WordPress posts can return 404 errors because of problems with rewrite rules in your .htaccess file. In most cases, you can fix the problem by updating your permalink settings.

Simply go to Settings » Permalinks in your WordPress admin, and click on the ‘Save Changes’ button.

There is no need to make changes to the permalink settings themselves. This will update your permalink settings and flush the rewrite rules.

In most cases, this solution fixes the WordPress posts 404 error. However, if it does not work for you, then you probably need to update your .htaccess file manually.

Method 3: Update the WordPress .htaccess File

Before you start, make sure to back up your WordPress .htaccess file first. If something goes wrong, you can easily restore the original file.

Now, you will need to connect to your server using an FTP client like FileZilla or the File Manager app in your WordPress hosting dashboard.

Next, you will need to find and edit the .htaccess file, which is located in the same location as folders like /wp-content/ and /wp-includes/.

Simply right-click on the file and select ‘File permissions.’

You can make the file writeable by changing its permissions to 666.

Simply enter ‘666’ into the ‘Numeric value’ box and then click on ‘OK’.

Then, you need to repeat the steps in the first method of our tutorial. Once you have done this, don’t forget to change the permissions back to 660.

You can also edit the file and add code to it.

Once you have opened the .htaccess file with a text editor, simply insert this code:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Method 4: Contact Your Hosting Provider

If neither of the solutions above has fixed the WordPress posts returning 404 error, then we recommend contacting your WordPress hosting provider. There may be an error on their end, or they might be able to help you troubleshoot the problem.

Please also see our guide on how to properly ask for WordPress support and get it.

Method 5: Enable mod-rewrite (Local WordPress Installation)

If you are using a local server for testing purposes, then you will need to enable mod_rewrite in the Apache configuration of your MAMP, WAMP, or XAMPP site.

This will allow WordPress to generate clean URLs and prevent the 404 error for posts and pages on your local server.

How you do this will differ by the platform you use. People using XAMPP can open their control panel and click the ‘Config’ button within Actions. Then, select ‘Apache (httpd.conf).’

Next, you will need to find this line #LoadModule rewrite_module modules/mod_rewrite.so and remove the ‘#’ to uncomment it.

This will load the mod_rewrite.

Then, find all instances of AllowOverride None and change them to AllowOverride All.

The ‘All’ value means that all directives can be overridden.

Once done, you can save the httpd.conf file and close it. After that, in the XAMPP control panel, click ‘Stop’ on the Apache module and ‘Start’ again to restart it.

Then, go back to your admin dashboard to see if your permalinks are working.
