描述
Custom 404 Pro replaces WordPress’s default 404 behaviour with a proper redirect. Instead of leaving visitors on a dead-end error page, you can send them to any page on your site or an external URL — with the HTTP status code of your choice.
Redirect Modes
- WordPress Page — pick any published page from a dropdown; the plugin redirects to it automatically.
- Custom URL — enter any absolute URL to redirect 404s off-site or to a specific path.
- HTTP Status Code — choose 301, 302, 307, or 308 to match your SEO or caching requirements.
404 Logging
When logging is enabled, the plugin records every 404 hit to a database table so you can see exactly what is broken:
- Request path
- Visitor IP address (can be disabled for privacy/GDPR compliance)
- Referrer URL
- User agent
- Timestamp
Logs are searchable and can be deleted individually, in bulk, or all at once. They can also be exported as a CSV file.
Email Notifications
Optionally receive an admin email each time a 404 is logged. Designed for low-traffic monitoring — if you expect high 404 volume, keep this off to avoid inbox flooding.
Multisite Support
Works correctly on WordPress Multisite installations — activation creates the logs table for each site in the network.
Multilingual Support
Compatible with Polylang and WPML. The redirect page is resolved to the correct language variant for the current visitor automatically.

安装
- Upload the
custom-404-profolder to the/wp-content/plugins/directory, or install it directly from the WordPress Plugin Directory. - Activate the plugin from the Plugins screen.
- Go to Custom 404 Pro Settings Global Redirect and choose a redirect mode (WordPress Page or Custom URL).
- Optionally, go to Custom 404 Pro Settings General to enable logging and email notifications.
常见问题
-
Does this plugin work with page caching plugins?
-
Yes, but make sure your caching plugin is not caching 404 responses. If it is, the redirect may not fire. Check your caching plugin’s exclusion settings and add 404 status codes or the affected paths to the exclusion list.
-
Why is the 404 redirect not working with the Divi theme?
-
Some users have reported a conflict with the Divi theme. Try switching to a default WordPress theme to confirm the plugin is working, then disable other plugins one by one to isolate the conflict.
-
Can I disable IP logging for GDPR compliance?
-
Yes. Go to Settings General and uncheck Log IP. All future log entries will record
N/Ainstead of the visitor’s IP address. Existing entries are not modified. -
Why are my settings not saving after a reinstall?
-
Always uninstall the plugin from the Plugins screen (do not delete the folder directly from the server). Deleting the folder bypasses the uninstall hook and leaves orphaned data in the database. Reinstalling over stale data can cause unexpected behaviour.
-
How do I report a bug or request a feature?
-
Please open an issue on GitHub. The WordPress.org support forum is not monitored.
