Yes, I disabled the social sharing options everywhere I found one. Also in the Item view options. It seems to have something to do with the K2 plug-in´s, but even when I disable the K2 Plug-In´s the link appears in after the content. Here is some code from the Firefox Web-Developer Inspektor:
<!-- Plugins: AfterDisplayContent -->
<!-- K2 Plugins: K2AfterDisplayContent -->
<a id="modalClick" class="modal" href="#itemSocialSharing" rel="{size:{x: 360, y: 38}}">
Click me
</a><div class="clr"></div>
How can I remove this? And where is this file with the source code?
