new wiki, no users

I performed a raw install: installed xwiki version 0.9.840 fresh on a Fedora Core Linux box with mySQL 4.0.26 and Tomcat 5.02. After I finally figured out how to install mySQL everything went smoothly. My wiki is up and running, and I started using it and building pages. But I noticed that everything I was doing is as the user: XWikiGuest. I want to create user accounts, and disable editing for anonymous guests. So, I click on "register" it takes me to a completely blank page. Just exactly like the blank pages you have when you've got a page and haven't put anything on it yet. So, I click on "edit this page" and it looks exactly like I'm editing a normal page - in fact it lets me edit the page. But no way to register new users. So, I go to the user's page: xwiki/bin/view/XWiki/XWikiUsers and it is completely blank too. Exactly like the above, I can edit it and do what I want on it, but no user stuff. So, I go back to my main page and click on "log in" and I try out the Admin password that is advertised on the support site user: "Admin" password: "admin" - and no dice. It grinds away for 1 split second and gives me back my log-in screen with the words I just typed in missing. No errors, nothing about bad passwords, nothing. I looked all over the documentation and couldn't find anything helpful. Ever seen this problem before? Is there something somewhere on the documentation site that I could paste into those two pages, using "edit page" to make them work? Thanks Kevin Miller
