title: my IDE is shown as simple text editor. No colors and no auto-complete
body: <p>I tried everything written here.</p>
  <ul>
  <li>restart</li>
  <li>setting root folder</li>
  <li>checking power safe</li>
  </ul>
  <p>But it was not solved</p>
  <p>My screen does not show any color. Everything is white and black.
  Control space is not working and there is no code completion.</p>
