So, I installed VaultWiki according to the installation directions on the web site.
However, I know have a top level Navigation category for Wiki that gives me a 404 error.
I can navigate directly to one of the forums underneath the wiki.
Since there is no showwiki.php in the forums directory after install, I figure I must have incorrectly configured something.
P.S. Also, how can I change my user name? I used my e-mail for ease of remembering, but I can't display a different name for posting.
