I'm new to K2 and trying to build a blog with it. On the main page i now show some articles from a categorie. But under the content of an article there are a couple of white lines i wanna remove. How do i do this ?

I looked in com_k2/default/category_item.php and see the lines :

<!-- Plugins: AfterDisplayContent -->
<?php echo $this->item->event->AfterDisplayContent; ?>

<!-- K2 Plugins: K2AfterDisplayContent -->
<?php echo $this->item->event->K2AfterDisplayContent; ?>

What does these AfterDisplayContent do and what can i do with it ?

And i also missing the socialmedia links under my article.

Please post a link to the site if it is live so people can use firebug
