TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site owners, especially eCommerce and content sites with changing URLs, who want broken links handled automatically. It solves the problem of 404 errors sending visitors to the wrong page by matching them to the correct destination using a multi-engine matching and spell-checking pipeline instead of defaulting to the homepage.

  • 7-engine matching pipeline
  • Levenshtein distance + N-gram spell-checking
  • Per-engine confidence thresholds
  • Manual redirect editor with bulk actions
  • CSV/JSON import/export (Redirection format)
  • HTTP status codes (301, 302, 410, 451)
  • Google Search Console integration
  • WP-CLI subcommands

Frequently Asked Questions

Common questions about 404 Solution

Redirection is a manual redirect manager — you write the rules, it applies them. That is useful when you know in advance which URLs will break. 404 Solution handles the URLs you don't know about: it automatically finds the right destination using a 7-engine matching pipeline and a spell-checking algorithm. Example: If a visitor types /prodcut/awesome-item, Redirection does nothing unless you manually created that specific rule. 404 Solution finds /product/awesome-item automatically. The two plugins are complementary. Many sites run both: Redirection for planned migrations and 404 Solution for everything else.
404 to 301 redirects ALL 404 errors to one fixed destination (usually the homepage). 404 Solution finds the actual page the visitor was looking for. Sending visitors to your homepage is poor UX and can create soft 404 problems in Google Search Console.
WP 404 Auto Redirect uses keyword matching, which works when the URL contains recognizable words from a post title. It fails on character-level typos — a URL like /prodcut/ has no keyword that matches "product." 404 Solution adds Levenshtein spell-checking, which catches transpositions and typos regardless of whether the keywords match. It also includes: full 404 logging, manual redirect management, CSV import/export, 410/451 status codes, GDPR IP hashing, debug logging, REST API, and WP-CLI support.
301 (permanent redirect), 302 (temporary redirect), 307 (temporary, method-preserving), 308 (permanent, method-preserving), 410 Gone (correct response for permanently deleted content — better for SEO than a 301 to homepage), 451 Unavailable For Legal Reasons, and Meta Refresh (client-side HTML redirect). Using 410 instead of redirecting deleted content to your homepage produces better results in Google Search Console and prevents soft-404 indexing.
No. The matching pipeline only runs when a genuine 404 occurs — normal page loads are unaffected. For large sites, 404 Solution uses N-gram indexing and caching tables to keep matching fast. Once a redirect is established, subsequent hits are served from the redirect table directly, bypassing the pipeline.
Yes. 404 Solution indexes WooCommerce products, product variations, product categories, and tags. When a product URL changes or a product is deleted, the appropriate redirect is created automatically.
404 Solution detects when a destination post is trashed or deleted and flags the redirect. Redirects pointing to deleted content are highlighted in the redirect table so nothing slips through unnoticed. The daily maintenance cron automatically removes orphaned auto-redirects.
Yes. 404 Solution imports CSV and JSON in the Redirection plugin's export format. It can also directly import from Rank Math, Yoast SEO, AIOSEO, and Safe Redirect Manager's database tables from the Tools tab.
Yes. IP addresses are hashed using a one-way algorithm before storage; the original IP is never written to disk. Log retention limits are configurable. By default no data is transmitted to external servers. The "Help the developer by sending error logs" admin checkbox (default off) and the uninstall feedback modal are the only opt-in paths that send data to the plugin author's reports server. See the plugin's privacy policy stub at docs/privacy.md for the retention period for rows keyed by site_url, the data-subject erasure path, and the processing region for the reports endpoint.
Yes. Manual redirect rules support full regular expression syntax for source URLs. Capture-group replacements can use either full HTTP(S) destination URLs or site-relative paths such as /archive/$1.
