Custom 404 Handler

This plugin allows you to take full control over how your WordPress site handles 404 (Not Found) errors. Instead of the default theme’s 404 page, you can:

• Display a Custom 404 Page: Choose any published page on your site to serve as your 404 error page.
• Log 404 Errors: Keep track of which URLs are causing 404 errors, including the referring URL, IP address, and user agent. This helps identify broken links or malicious activity.
• Analyze Logs: View statistics like the most frequent 404 URLs and top referrers directly in your WordPress admin.
• Create Automatic Redirects: Easily set up 301 (permanent) or 302 (temporary) redirects for specific 404 URLs to send visitors to the correct content. Track redirect hits.
• Export Logs: Download your 404 error logs as a CSV file for external analysis.
• Optionally Redirect All 404s to Homepage: A simple option to redirect all 404 errors directly to your site’s homepage.
• Add noindex Tag: Automatically add a noindex, follow meta tag to your 404 pages (custom or default) to prevent search engines from indexing them.
