Okay, before making any attempt to edit your blog template, I strongly insist you to make a back up template, just in case if later, you want to revert back the template to the first condition.

Look around for the code:

Okay, now let’s play around with the code template. By pressing Ctrl + F, now find the code below:

<data:post.body/></b:if>

or

<data:post.body/>

</b:if>

Place the code section:

<data:post.body/>

Place the code section

</b:if>

The code section:

<b:if cond='data:blog.pageType == &quot;item&quot;'>

<div class='related_posts'>
