Missing the button bar

Hello, I recently inherited an xwiki site. I was able to use the superadmin to login to the site (thanks, Sergiu!), but once logged in, the button bar containing the Home, Blog, Knowledge Base, Search, Admin, Doc, and Register buttons is not visible. I'm guessing this is a skin issue, but I don't know where to start. I'm using tomcat to serve up xwiki.war for the site, and I don't have the original code or site which was bundled into the war file. Any help would be appreciated, and thanks in advance!
