It looks like they just changed the class names from childforum to forumbits. I haven't done much checking, but I changed the name real quick and it seemed to work:

.forumbits ol {
  float: left;
  width: 100%;
  margin: 0;
  padding: 0;
}
.forumbits li.forumbit_post {
  float: left;
  width: 50%;
  margin: 0;
  padding: 0;
  clear:none;
}
