Hi @andrei202 ,
Thank you for your reply.
Server side is configured correctly as I checked with the support team (Kinsta server).
Also, the 404 has a nice error for the user, you can check the image here:

Now you can’t test the permalinks as I’ve set the redirects. But anyways this seems to be a plugin problem, it translated part of the word in permalink and that link became unreachable. Any ideas to solve this because my redirect solution is just a workaround?
