how to configure Tomcat manager on each instance?

I got Tomcat Instance running and as well the root with Tomcat manager. I am following the following tutorial to configure Tomcat manager on my new Tomcat instance: http://grokandroll.com/tomcat/configurating-tomcat-manager.html

After configuring and pointing to www.website.com:8081/manager i got nothing....blank, no errors,no login...and nothing in Logs. my app runs at www.website.com:8081/sample

Any ideas on how to troubleshoot this?

p.s. manager.xml

   <Context path="/manager"          
      docBase="/usr/local/mywebbase/webapps/manager"        
      debug="0"     
      privileged="true">      

   <ResourceLink name="users"      
      global="UserDatabase"       
      type="org.apache.catalina.UserDatabase"/>      
      <!--<Valve className="org.apache.catalina.valves.RemoteAddrValve"           allow="127.0.0.1,192.168.100.100"/>-->
