A 404 File Not Found error in WordPress basically means your server can’t locate the page or resource you’re trying to reach. It usually pops up if the URL is wrong, or if the content was moved or deleted.
Common Causes:
- Broken permalinks or changes to your permalink settings.
- A post or page that’s been deleted or moved without updating the link.
- Typos or incorrect URLs entered by visitors.
- Missing files (like images or documents) on your server.
How to Fix It:
Check and Refresh Permalinks
- In your dashboard, go to Settings → Permalinks.
- Click Save Changes without making edits. This often refreshes the structure and fixes 404s.
Add a 404.php Template
- If your theme lacks a custom 404 page, create a 404.php file in your theme folder (you can copy from index.php as a starter).
- This way, visitors see a friendly message instead of an empty screen.
- See the WordPress docs on creating 404 pages for details.
Review Your .htaccess File
- In your WordPress root, open .htaccess and make sure it has the standard rewrite rules for permalinks. If you’re not sure, get help from your host.
Verify Content Exists
- Double-check that the file or page causing the 404 actually exists on the server. Use FTP or your file manager to confirm.
Test Themes and Plugins
- Sometimes themes or plugins trigger 404 issues. Try deactivating them one by one to identify conflicts.
Server Configuration
- If you manage your own server, ensure Apache or Nginx is set up to respect your rewrite rules.
