Erase Subscribe to: Posts (Atom)

    Go to dashboard/ template/ edit HTML
    Click the 'Expand Widgets Templates' box
    Find:




    <b:if cond='data:blog.pageType != "item"'> <!-- Blog feed links -->
    <b:if cond='data:feedLinks'>
    <div class='blog-feeds'>
    <b:include data='feedLinks' name='feedLinksBody'/>
    </div>
    </b:if>




Remove this line:


   <b:include data='feedLinks' name='feedLinksBody'/>



That should remove Posts (Atom).
