Hello,

It’s virtually impossible that redirections remains after uninstalling this plugin, because redirections are done on-the-fly, via the code, when a 404 page is about to be displayed.

So it means you have another plugin or code that redirect/change your pages canonical (which should be avoided at all cost!), and is probably responsible of the mess you described.

Google will never dereference living pages, unless you redirect them. Or change canonical tags, which this plugin does not do.

Regards.

Hello,

Thank you for reconsidering your rating, it wasn’t necessary but still appreciable.

I just felt bad for your website. If one day you have to deal with redirections/Google Seach Console again, one advise I can give you is to never, ever, try to change the canonical tags. It’s a trap that will lead to more issues.

You should leave WordPress generating the canonical as it does. Instead, setup manual redirections if you make important change to your permalink structure, or change to important pages. Either using Yoast, Simple Redirect, Redirections or RankMath redirections….

For the rest of 404 you’re not aware of, or malformed external links that lead to your website: WP 404 Auto Redirect to Similar Post will cover your back, while still letting other plugins mentioned above do their job without disturbing them.

Regards.
