I have installed the latest release candidate according to the automatic install instructions, and the setup appears to have at least partially failed.
After the configuration process, I moved the local settings file to main wiki directory as specified (http://www.mindvector.dreamhost.com/wiki/), and followed the link from the configuration screen. Instead of the wiki as expected, I recieved a 404 error in IE. Using Mozilla I went to the wiki directory, and found that http://www.mindvector.dreamhost.com/wiki/ was redirected to http://www.mindvector.dreamhost.com/wiki/index.php/Wiki/index.php and the message "No input file specified." is displayed.
So the Wiki is there?, but somehow is confused as to exactly where 'there' is it appears.
