title: Heroku - apple-touch-icon-144x144-precomposed.png isn't precompiled

  <p>I got heroku to start running, but then it stops when I get ti to display a parameter from a  database. This is all working locally. I couldn't find what could be the issue. Some people said to restart heroku, which I did, to no avail. </p>
