Helly, Dinsan! I see you are using the quick adsense plugin. Simply go to the adsense plugin settings and replace your adsense code with the following.

<div style=”float:none;margin:0px 0 0px 0;text-align:center;”>
<script async src=”//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script>
<!– GChrome-Comments –>
<ins class=”adsbygoogle”
style=”display:moz-block;width:336px;height:280px”
data-ad-client=”ca-pub-30906677723#####”
data-ad-slot=”4872089213″></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

Just replace data-ad-client=”ca-pub-30906677723#####” with your existing ad-client ID. I blocked out the last 5 digits for your privacy.

Let me know if this helps. thanks!
