I have been using the above mentioned plugin on this website (you will get to the 404 page when you click on the link) and it works fine. The only thing that is missing is a report of how visitors came to see the 404 page. That would be a huge advantage, so if Artbees were to truly consider this option, please keep this in mind too. Thanks in advance!
Hello @Romke_Jellema, feel free to checkout the WP plugin “Redirection” by John Godley. There you get a good overview and - as far I know (no guarantee) - it is GDPR compliant (if you don’t use IP storing).
But also from my side: I would prefer to have the chance to change the 404 page in the theme customizing.
Thanks, Sven! I will check it out.
