Twitter Tweet Button does not count

Question

I am using the official Tweet Button from Twitter to allow users to share my site.

The button itself is working just fine, however the counter doesn\'t work and stays at

Answer 1

you must use both "data-count" AND "data-url" if you want to show a count and there is a url shortener involved (and there always is):

  data-url="http://dev.twitter.com/pages/tweet_button"
  data-count="vertical"
