After enabling comments on a blog post and adding one, displaying the full post does not work. The html page only countains a couple tags with the last comment. For example, it gives pages like this:

<div class="comment comment-new">
  <a id="new"></a>
  <span class="new">new</span>

<h3 class="title"><a href="/stupid-javascipt-email-validators#comment-5" class="active">javascript can be annoying</a></h3>
    <div class="content"><p>It really can.</p>
</div>
    <div class="info">

See for example here.

That's it, no other tags for the page. Disabling comments makes it work again. The content is there, it shows on the main blog page.
