title: Hudson Error Message: Admin user is missing Administer permission
body: <p>I'm getting an error message in Hudson when I try to access the configuration page saying:</p>
  
  <blockquote>
    <p>Admin user is missing Administer permission</p>
  </blockquote>
  
  <p>I'm not aware of any changes in the configuration since it last worked. In the config.xml file the admin user appears to be set up correctly:</p>
  
  <pre><code>&lt;permission&gt;hudson.model.Hudson.Administer:admin&lt;/permission&gt; 
  </code></pre>
  
  <p>Any ideas on how to fix this?</p>
