How to Fix WordPress Posts Returning 404 Error: 4 Easy Methods

As we've experienced 404 errors ourselves, we know how to tackle and fix this issue when it occurs. Usually, Google Search Console provides this report. However, it is good practice to check for 404 errors regularly.

We have used these 4 methods to fix WordPress posts returning 404 errors-

• Method 1: Check for Plugin or Theme Conflicts and Custom Code Issues
• Method 2: Fix Your Permalink Settings
• Method 3: Update the WordPress .htaccess File
• Method 4: Contact Your Hosting Provider

Now, let's see how to apply these methods-

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

First and foremost, you need to check if you have any plugin or theme conflicts and if you have made any errors while putting in any custom codes.

These can interfere with permalinks and cause a 404 error. Plugin conflicts can happen when you install the same type of plugin. For example, if you install both Dokan Multivendor and WCFM, they will show a conflict.

One way to solve the plugin conflict is to deactivate the plugins one by one. Plugins can sometimes disrupt how WordPress handles links.

You need to check by activating the plugin one by one to see if any of the plugin triggers a 404 error on your website. If the issue reappears after activating one of the plugins, then it is the plugin that is causing the problem.

If the plugin is not important then you can ditch that plugin. Otherwise, you need to contact the developer or support team to solve the issue.

The same goes for your WordPress themes as well. You need to install another theme from Appearance–> Themes like Twenty-Twenty-Four to see if the 404 error is gone.

If it is gone, then your site has a potential conflict with your theme. You need to contact the theme developer or their support to solve the issue.

If you have inserted any custom codes into your website, then you need to check that as well. If you have used a plugin like WPCode, then there is a rare chance that you have any errors in the custom code. Because it will show any error in the code and will automatically deactivate the custom code.

Method 2: Fix Your Permalink Settings

The next method is to 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.

Just go to Settings–> Permalinks, 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. This precaution allows you to easily restore the original file if something goes wrong.

Use an FTP client like FileZilla or the File Manager in your WordPress hosting dashboard to locate the .htaccess file and download a copy to your local machine.

Next, connect to your server using your FTP client or File Manager and log in. Navigate to the root directory of your WordPress installation, where you’ll find folders such as wp-content and wp-includes.

Locate the .htaccess file in this directory. If it’s not immediately visible, ensure your FTP client is set to show hidden files.

Once you have found the .htaccess file, you need to make it writable. Right-click on the file and select ‘File permissions' or ‘Change Permissions'. Enter 666 in the ‘Numeric value' box and change the permission.

Then click ‘OK'. This change allows you to edit the file.

Open the .htaccess file with a text editor. Many FTP clients provide a built-in text editor, or you can download the file and use a local text editor like Notepad++ or VS Code. Insert the necessary code into the file. For instance, you might add the following:

apacheCopy code# BEGIN Custom Rules
<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 Custom Rules

After editing, save the changes and re-upload the file to the server if you edited it locally. Verify that your site functions correctly with the new .htaccess rules.

Finally, for security reasons, revert the file permissions of the .htaccess file to 660. Right-click on the .htaccess file again, select ‘File permissions', enter 660 in the ‘Numeric value' box, and click ‘OK'. This step secures your .htaccess file against unauthorized changes.

Method 4: Contact Your Hosting Provider

Unfortunately, if none of the above methods works and you still have 404 errors on your website, then you need to contact your hosting provider. There may be an error on their end and they will help you fix it.

Hopefully, then you won't have the 404 error on your website.
