Hi, the problem is not in the update, it was very confusing until we found the real cause of the problem , you’re using the code in a wrong way:

.post-sharing-bd ul {
  float: left;
{

While it should be:

.post-sharing-bd ul {
  float: left;
}

PlPlease make sure always that the start and the end of the code are put correctly.. Now everything work fine 🙂
You confused us with this strange issue 🙂
