I am blind or something but i can't find it in source code o.O

Look at the forum tab. It only shows up there.

You've just got code for ads multiple times and it's malformed. Somewhere, you've put this:

<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script></div><!-- end: header -->
<!-- start: adsmnger --> 
<center> 
<a href="<script type="text/javascript"><!--
google_ad_client = "ca-pub-3429924407136831";
/* ad1 */
google_ad_slot = "1456617112";
google_ad_width = 728;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>" target="_blank"><img src="<script type="text/javascript"><!--
google_ad_client = "ca-pub-3429924407136831";
/* other ads */
google_ad_slot = "0108093809";
google_ad_width = 728;
google_ad_height = 90;
//-->

You've got the same code 5 times, and the HTML is broken. Remove this code and add it again.

Let me try it.
