What happens if you just put some static html in there, does that render out on page.
Can you show us the code for any template and chunks you might of changed.
are you sure, this is an articles - container, where you have that code?
I'm pretty sure that it is. I mentioned before that I only changed the css yet I failed to mention that I also use my own template. Though that should not be the cause of why content is not showing.
what do you get with
<h1>TEST</h1>
classkey:[[*class_key]]<br />
<h2>children</h2>
[[getResources? &parents=`[[*id]]` &showHidden=`1` &tpl=`@INLINE [[+pagetitle]]`]]
[[!+page.nav:notempty=`
<div class="paging">
<ul class="pageList">
[[+paging]]
</ul>
</div>
`]]
