When I am with the default mode on permalink my page works but when I use any mode it shows the message:
The requested URL was not found on this server.
Apache/2.4.38 (Debian) Server at iutdv.dv.utfpr.edu.br Port 80
And it seems weird because I can’t tell my client “Your contact page is ‘sdadasdad.com/?page_id=123′” (example). It was suposed to be /contact, right?
