Essential after a migration
When a site's domain changes, or numerous pages get new URLs, this extension saves hours of work and keeps your SEO stress-free.

Plugin is broken. Don't install it
Unfortunately, I have to warn that this plugin is full of bugs and installation is not recommended. I've been trying to point this out to the developer and get them fixed. It's been almost 2 months, and basic functions of the plugin are still broken. Very sad to see this, as the idea of the plugin has potential.

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!
