title: Pycharm 2.7: Internal HTTP server disabled
body: <p>I have installed pycharm 2.7 and each time I run it, the following message is shown on the left top corner in a red box:
  Internal HTTP server disabled.
  Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart pycahrm.</p>
  
  <p>And I checked firewall settings. I didn't see anything that might have caused this. What should I do?</p>
