There seems to be a bug that's messing some posts.

One of the post have this body:

<iframe height="637" allowTransparency="true" frameborder="0" scrolling="no" style="width:100%;border:none" src="http://laibcoms.wufoo.com/embed/z7x3p3/"><a href="http://laibcoms.wufoo.com/forms/z7x3p3/" title="Contact Form">Fill out my Wufoo form!</a></iframe>

<small><a href="http://wufoo.com/">Powered by Wufoo</a></small>

And it produces this:

The requested URL /blogs/<a href= was not found on this server.

The other post (which I already edited in my live site) is this:

All content in <span xmlns:dc="http://www.purl.org/" property="dc:title">Laibcoms.asia</span> created by <a xmlns:cc="http://creativecommons.org/ns#" href="http://laibcoms.asia" property="cc:attributionName" rel="cc:attributionURL">JC John Sese Cuneta &amp; Sherlene Maquiling Solatorio</a> is licensed under a <a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/ph/">Creative Commons Attribution-Share Alike 3.0 Philippines License</a>.

And another post:

<div class="center" style="margin: 0 auto; text-align: center;">
<script type="text/javascript" src="http://disqus.com/forums/laibcoms/combination_widget.js?num_items=23&amp;color=red&amp;default_tab=recent"></script>
</div>

All of the above works fine prior to 3.2.0-beta upgrade.
I'm not sure how many posts are currently not displaying as intended.

I tested with:
[list]

production site: http://laibcoms.asia/blog/

localhost

my own skins

default skins

[/list:u]

Also, the b2evo group I used for testing have all "xhtml" settings into "Basic" and all checkboxes 'unchecked' for Security filters and Antispam filters.
