URL:you typed the wrong one can redirect to the page you wish. I recommend a plugin called 404 Solution. Previously, I used a plugin in WordPress called Redirecter or 404 redirected, both names exist. Tyvärr har den inte uppdateras på länge. 404 Solution är som en kopia på Redirecter men har mycket bättre support and updates. I have not found any difference between these two plug:you but maybe there.
An additional merit of this plugin is that you can see in the log what people are trying to write and can then redirect them to the page probably are looking for. One can also see how hackers trying to enter.
