title: MODx Plugin does not get fired (with no event)
body: <p>I created a test plugin and activated <strong>ALL events</strong> in the "System-Events" Tab. The Plugin looks like so:</p>
  
  <pre><code>&lt;?php
  error_log('test_plugin: ' . $modx-&gt;event-&gt;name);
  </code></pre>
  
  <p>thats it. </p>
  
  <p>I'm following the error.log via <code>tail -f /var/log/error.log</code> and I get several entries when I'm reloading a page in the <strong>backend</strong> (which is perfect)</p>

  <p>But when loading a page in <strong>FRONT-END</strong> I get <strong>NOTHING AT ALL</strong>.</p>
  
  <p>Any ideas? I'm using <strong>Revo 2.2.14-pl</strong></p>
