first go to Configure/Article types and activate comments for 'page' article type (by clicking on the red circle), and then go to the template set_thejournal/article.tpl and add these lines
<div id="comments">
{{ include file="set_thejournal/_tpl/article-comments.tpl" }}
</div>
just under this line (should be line number 51 if you haven't changed anything)
{{ include file="set_thejournal/_tpl/article-fullwidth.tpl" }}
