  <p>I've been out for awhile in using heroku... and after the big comeback, I encountered this error.</p>
  
  <p>I am outdated already in terms of present Heroku news.</p>
  
  <p>I hope somebody could give me a suggestion, solution or issues involved.</p>
  
  <p>Thanks.</p>
  
  <p>EDIT:</p>
  
  <p>The logs says...</p>
