When I'm sharing an article to facebook, then the number in the button is always 0 (zero). Can you help me please? Thank you.

Hi. How do you generate this button? This is not coming from K2. You can disable this buttons and use K2's sharing options. Also ensure that you are using the latest version of K2.

I'm using the latest K2 version, and these buttons are from the K2 view category settings. I'm not using any extra plugin for these things.

The following is inside the "Sharing options" of K2.

<script type="text/javascript" src="w.sharethis.com/button/buttons.js">
<script type="text/javascript">stLight.options({publisher: "ur-c64aa0b1-b15d-c411-f5fd-ee8e97f0f64d"}); </script>
<span class='st_facebook_hcount' displayText='Facebook'></span>
<span class='st_twitter_hcount' displayText='Tweet'></span>
<span class='st_plusone_hcount' displayText='Google +1'></span>

I updated today my K2 to version 2.5.6 and everything works fine about sharing. Great job.
