As I'm going to be the only user, I have disabled the ACL.
But now I don't see how I can configure the wiki. The "Login" button has gone, as expected, but so did the "Admin".
That's why useacl is recommended even for single user installs. Without it you can only configure the wiki by editing the config files.

Not possible.
