title: Brackets - DOM Agent Needs To Be Enabled First
body: <p>Brackets live preview doesn't appear to be working correctly. Upon clicking live preview, the yellow lightening bolt icon is only half filled. The browser tries to start loading the live preview, however it is stuck on the brackets waiting... page.</p>
  
  <p>The URL IS: file:///C:/Program%20Files%20(x86)/Brackets/www/LiveDevelopment/launch.html</p>
  
  <p>I've opened up the brackets devtools (localhost:9234/devtools/devtools.html?ws=localhost:9234/devtools/page/ec744244d7ea99e5c99ffeb2ff42872e) to look for errors, and the browser console reads:</p>
  
  <pre><code>enable failed on agent css ErrorNotification.js:117
  
  DOM agent needs to be enabled first. Object {code: -32000, message: "DOM agent needs to be enabled first."} 
  Object {method: "CSS.enable", id: 6, params: Object} ErrorNotification.js:117

  <p>I've Tried:</p>
  
  <ul>
  <li>Rebooting</li>
  <li>Uninstall / Reinstall</li>
  <li>Removing ALL plugins</li>
  </ul>
  
  <p>I'm out of ideas. Anyone able to help?</p>
