title: Jenkins - Plugins not installing and jobs and features are missing after upgrade.
body: <p>I'm using latest Jenkins (v 1.590) LOL, but Jenkins official site say: 1.588. I'm 200% sure that I did see 1.589 and 1.590 few days back on Jenkins official download site(when I wanted to upgrade Jenkins to newer version).</p>
  
  <p>This is what I see at the bottom of my Jenkins instance page.</p>

  </code></pre>
  
  <p>Now, the issue I'm facing is: Since I upgraded few of the plugins and Jenkins itself recently, some of the jobs are missing (I see this can happen during upgrades but upgrading to latest Jenkins should fix it and I'm two steps ahead of what Jenkins has on their official site, right):</p>
  
  <ol>
  <li>I go to Manage Jenkins, Manage Plugins, Go to Available tab, check mark bunch of plugins to install (Artifactory, Maven project plugin etc ) and restart Jenkins using Jenkins GUI interface (which happens automatically once plugins are downloaded/installed in Jenkins GUI). After the restart, I do the same to see whether the plugin is now showing under "Installed" tab or not, but to my luck, it's still showing under "Available tab" and is NOT listed under "Installed" tab. If I open an existing job's configuration OR create a new job, the features available due to installed plugins are <strong>NOT</strong> visible i.e. if I installed Maven Project Plugin, I don't see an option to create a Maven style(2/3) project job while creating a new job.</li>
  </ol>
  
  <p>I see valid .<strong>jpi</strong> files for respective plugins in plugins folder in JENKINS_HOME and there are some .pinned files as well. I have tried this a couple of times but the plugins are not visible once installed. Installation doesn't give any error during the whole operation.</p>
  
  <p><strong>Jenkins system log</strong> file (upon Jenkins restart) is attached (NOTE: Use slow download button to see/download this log file).</p>
