title: Error 503 -service unavailable on wamp
body: <p>I installed <code>Wamp</code> on my system and it worked perfectly on <code>Windows 8</code>. I later installed <code>Ubuntu</code> alongside it and since then i am getting a 503 service error on my localhost. 
  I tried removing ubuntu and reinstalling windows 8 but it did not help either.
  Can someone tell me how to rectify the error?</p>
