Fix WordPress Posts Returning 404 Error

Let’s explore the easiest ways to fix WordPress posts that return a 404 error, along with some common reasons why it happens.

Common Reasons

  • Corrupted Permalink Settings – Broken permalink configurations can cause URLs to stop working.
  • Missing or Corrupted .htaccess File – A missing or incorrect .htaccess file can disrupt URL rewriting.
  • Plugin or Theme Conflicts – Plugins or themes may interfere with permalink functionality.

Saving your WordPress permalink settings can resolve the WordPress Posts Returning 404 Error

You don’t need to modify the permalink settings themselves. Simply saving them updates your permalink settings and flushes the rewrite rules. In most cases, this resolves the WordPress 404 error for posts.

2. Check and Update the .htaccess File

The .htaccess file manages your website’s URL structure and permalinks. If it’s corrupted or misconfigured, it can cause 404 errors. Here’s how to check and update it to fix the issue.

Use an FTP client (like FileZilla) or the file manager in your hosting control panel to access your site’s root directory.

If your .htaccess file is corrupted or missing, replace its contents with the following default WordPress rewrite rules:

PHP
# 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

After pasting the code, save the file and upload it to the root directory if you created a new one.

3. Disable Conflicting Plugins

WordPress plugins can sometimes interfere with your site’s URL structure, causing 404 errors. Temporarily disabling plugins can help identify the cause. Here’s how to do it:

  • Access your WordPress admin dashboard by logging in to your site.

After deactivating all plugins, check if the 404 error is resolved. If it is, reactivate each plugin one by one. When the error returns, you’ll find the conflicting plugin. Check for updates or contact the plugin developer for support.

4. Switch to a Default Theme

Sometimes, your theme could be causing 404 errors due to poor coding or compatibility issues. Switching to a default WordPress theme, like the “Twenty” series, can help determine if your theme is the problem.

Log in to your WordPress dashboard, go to “Appearance” in the sidebar, click “Themes,” and activate the Default Theme.

If switching to the default theme resolves the 404 errors, consider staying with the default theme or choosing another well-coded theme compatible with the latest WordPress updates.

5. Check Server Configurations

Server configurations can cause 404 errors. Ensure mod_rewrite is enabled (for Apache servers) or the correct rewrite rules are set (for Nginx). Check that your server runs a compatible PHP version and verify that it has proper server limits.

Review error logs for any related issues. If you’re unsure, contact your hosting provider for assistance. Proper server setup ensures WordPress can process URLs and prevent 404 errors.

Conclusion

404 errors in WordPress posts can usually be resolved by tweaking permalink settings or the .htaccess file. If these steps don’t solve the problem, further investigation into plugins or themes might be necessary.

By following these steps methodically, you should be able to get your site running smoothly again. Always back up your site before making any changes, as this can help you recover quickly if something goes wrong.
