Why Does WordPress Show 404 Errors After Changing Permalinks?
Permalinks determine how your website URLs are structured.
When permalink settings change, WordPress updates its rewrite rules. If these rules aren’t refreshed properly, your posts may return 404 errors even though they still exist in the database.
Common reasons include:
- Corrupted
.htaccess - Rewrite rules not updated
- Plugin conflicts
- Server configuration issues
- Incorrect file permissions
- Apache mod_rewrite disabled
The good news is that these problems are usually easy to fix.

Fix 1: Save Permalink Settings Again
This solves the problem in most cases.
Go to:
Settings → Permalinks
Without changing anything:
Click
Save Changes
WordPress automatically regenerates its rewrite rules.
Now visit one of your blog posts.
If it opens correctly, the issue has been resolved.
Fix 2: Repair the .htaccess File
If saving permalinks doesn’t work, your .htaccess file may be damaged.
Using File Manager or FTP:
Open:
public_html/.htaccess
Replace its contents with:
# 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
Save the file.
Then return to:
Settings → Permalinks
Click:
Save Changes
again.

Fix 3: Disable Plugin Conflicts
Sometimes SEO or security plugins interfere with permalink rules.
Temporarily deactivate all plugins except WordPress core.
Then:
- Test your posts.
- Reactivate plugins one at a time.
- Check when the error returns.
Once the issue reappears, you’ve identified the conflicting plugin.

Fix 4: Check Apache Rewrite Module
If you’re using Apache hosting, the mod_rewrite module must be enabled.
Without it, WordPress pretty permalinks cannot function correctly.
Ask your hosting provider to verify that:
- mod_rewrite is enabled
- AllowOverride is enabled
These settings are required for custom permalink structures.

Fix 5: Check File Permissions
Incorrect file permissions can prevent WordPress from reading rewrite rules properly, resulting in the WordPress Posts Returning 404 Error.
Recommended permissions:
Folders
755
Files
644
Using your hosting File Manager or FTP client:
- Open public_html.
- Right-click the file or folder.
- Select Permissions.
- Apply the recommended values.
Avoid using 777 permissions because they create serious security risks.
Fix 6: Verify WordPress Address and Site Address
Incorrect website URLs can also trigger permalink problems.
Navigate to:
Settings → General
Verify that both fields are correct:
- WordPress Address (URL)
- Site Address (URL)
Example:
https://yourdomain.com
Both URLs should match unless you’re intentionally using different locations for WordPress files.
After saving, test your posts again.
Fix 7: Reset Rewrite Rules
If saving permalinks didn’t work, manually reset the rewrite rules.
Go to:
Settings → Permalinks
Change the permalink structure temporarily to:
Plain
Save changes.
Now change it back to:
Post name
Save again.
This forces WordPress to rebuild its URL rewrite rules.

Fix 8: Switch to a Default WordPress Theme
Themes sometimes override WordPress templates incorrectly.
Temporarily activate a default theme:
- Twenty Twenty-Five
- Twenty Twenty-Four
- Twenty Twenty-Three
Visit several blog posts.
If the 404 errors disappear, your previous theme is likely causing the issue.
Update or replace the theme with a compatible version.
Fix 9: Contact Your Hosting Provider
If none of the previous methods work, the issue may be server-related.
Ask your hosting provider to verify:
- Apache mod_rewrite is enabled.
- NGINX rewrite rules are correct.
- .htaccess is readable.
- Server cache has been cleared.
- File permissions are correct.
Most hosting providers can quickly identify server-side configuration problems.

Clear All Website Caches
Caching plugins may continue serving outdated URLs even after you’ve fixed the issue.
Clear cache from:
- LiteSpeed Cache
- WP Rocket
- W3 Total Cache
- Hostinger Cache
- Cloudflare CDN
Then refresh your browser using:
Ctrl + F5
This ensures you’re viewing the latest version of your website.
Common Mistakes to Avoid
Avoid these common mistakes while fixing 404 errors:
- Editing
.htaccessincorrectly. - Forgetting to save permalink settings.
- Using incorrect file permissions.
- Deleting the
.htaccessfile without a backup. - Ignoring plugin conflicts.
- Skipping cache clearing.
- Using outdated PHP or WordPress versions.
Taking a systematic approach makes troubleshooting much easier.
