Overview
Stop losing visitors and search rankings to broken links. 404 Solution automatically redirects 404s to the right page — not just your homepage — using a 7-engine matching pipeline that includes a spell-checking algorithm to find what visitors actually typed.
Example: A visitor hits /prodcut/awesome-item (typo). Most 404 redirect plugins send them to your homepage. 404 Solution’s spell-checker finds /product/awesome-item and redirects them there automatically.

Works as expected; fast support!

I haven’t tried all of the features that this plugin has to offer as I intended to just use it temporarily to redirect users to a designated 404 page, but it does so much more. I really appreciate the logs that show me the crazy urls people/bots are trying to access. Had a minor issue with a php notice that I reported, and the developer quickly jumped on it and released an update. Kudos!
Thank you for your great plugin!!!!

P.S… Plus, when an issue did come up later, after I first did this review, the plugin author fixed it nicely in a timely manner…

Bug Fixes
- Fixed multisite activation/upgrade skipping orphaned table adoption — batch methods now run adoption after table creation, ensuring migrated data is recovered on multisite networks.
- Fixed DDL schema comparison failing on MariaDB servers that use
COLLATE=utf8mb4_unicode_ci(equals sign) instead of MySQL’sCOLLATE utf8mb4_unicode_ci(space), causing unnecessary schema rebuild loops. - Fixed
doEmptyTrash()executing an empty SQL query when called with an unrecognized sub-page parameter — now early-returns after logging the error. - Fixed logs URL filter failing when
logsidwas passed as a non-string type, causing a type error insanitizeForSQL(). - Fixed invalid UTF-8 byte sequences in captured URLs corrupting log INSERT queries — added
mb_convert_encoding()sanitization at the log entry boundary.
