hello I've followed the instructions and installed xwiki 1.8 enterprise. I used Leopard Server 10.5.6, Tomcat 5.5, PostgreSQL 8.3. Tomcat is running on port 8080. PostgreSQL has been running fine for Bugzilla, and xwiki database and xwiki user are created, and I can log into database using the new user ID. JDBC driver is place in the correct location. I didn't set TOMCAT5_SECURITY becos /etc/default directory does not exist. hibernate.cfg.xml and xwiki.cfg are changed according to instructions. Upon typing http://myservername.com:8080/xwiki, the URL becomes http://myservername.com:8080/xwiki/bin/view/Main/ , and the web browser displays a blank page. The page source is empty. There is no xwiki.log in Tomcat's directory, but catalina.out shows this : Mar 21, 2009 10:46:00 PM org.apache.catalina.core.StandardContext reload INFO: Reloading this Context has started log4j:ERROR
