title: "hudson.security.AccessDeniedException2: anonymous is missing the Overall/Administer permission" error in Jenkins
body: <p>To upgrade Jenkins from <code>version 1.466.2</code> to <code>version 1.557</code>, I replaced the old <code>jenkins war</code> file with <code>jenkins war</code> file in the directory <code>/usr/share/jenkins</code>. Then on restarting the jenkins from command line I started getting the new Jenkins <code>version 1.557</code>. But sometime later I messed with security part of it, I checked the security check box while configuring Jenkins. Now I am not able to use Jenkins, if I go to <code>myproject.com:3300</code> it gives me <strong>error:</strong> <code>hudson.security.AccessDeniedException2: anonymous is missing the Overall/Administer permission</code>. <br>To fix this error I found that I need to change <code>&lt;usesecurity&gt;</code> from true to false. But when I go to the <code>var/lib/jenkins</code> (which home directory of Jenkins) to edit config.xml. I am still seeing the old version <code>version 1.466.2</code> but in GUI at <code>myproject.com:3300</code> it shows new version.<br></p>
  
  <p>I am stuck here, please let me know what am I missing, how can I get it running.</p>
