Which Part Adsense Code To Remove

I am using a custom Blogger template and the Layout widgets are not working. I need to remove a Adsense Link ad.

I tried removing the code, but the whole site disappeared. Could someone tell me which part of the code should I delete.

The HTML code is:

<b:widget id='HTML3' locked='false' title='' type='HTML' version='1'>
<b:widget-settings>
<b:widget-setting name='content'>&lt;center&gt;&lt;script async src=&quot;//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js&quot;&gt;&lt;/script&gt;
&lt;!-- right links --&gt;
&lt;ins class=&quot;adsbygoogle&quot;
style=&quot;display:inline-block;width:160px;height:90px&quot;
data-ad-client=&quot;ca-pub-xxxxxxxxxx&quot;
data-ad-slot=&quot;xxxxxxxxx&quot;&gt;&lt;/ins&gt;
&lt;script&gt;
(adsbygoogle = window.adsbygoogle || []).push({});
&lt;/script&gt;&lt;/center&gt;</b:widget-setting>
</b:widget-settings>
<b:includable id='main'>
<b:if cond='data:title != &quot;&quot;'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div>
</b:includable>
</b:widget>

 

I have already fixed it.
