[xwiki-users] Can't see Wiki Manger

I created a new Wiki and installed the Wiki Manager Plugin (for mysql). I can see the default wiki page, but when I go to http://localhost:8080/xwiki/bin/view/WikiManager or /WikiManager/WebHome, there's a blank page. I have the xwiki-plugin-wiki-manager-1.4.jar, mysql-connector- java-5.1.6-bin.jar installed along with the application xar's. I've configured hibernate.cfg.xml file to use mysql. I've edited xwiki.cfg to use the wikimanager and applicationmanager plugins. I've set xwiki.virtual=1. I've given permissions to the mysql database. Any ideas on what I'm doing wrong?
