Starting on a new DokuWiki site, I setup the monobook theme and the configuration. I had not yet added any users.
If I set the configuration page to
$conf['userewrite'] = 1;
$conf['useslash'] = 1;
and click Login > Register New Account, I reach a 404 Error page. The URL it sends me to is
http://localhost/dokuwik/start?do=register (which does not work)
If I set both of these 2 variables to = 0, the URL it sends me to is
http://localhost/dokuwik/doku.php?id=start&do=register and the page loads fine.
