I’ve tried the one-click install and when I go to access my config URL it just says:

The requested URL /wiki/config was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Am I missing something?

You wait a few? I hadn’t tried the One-Clicks, but I’m sure everything’s queued and processed in intervals.

You’ll get an e-mail telling you when the setup is complete – then you can access it.
