Jesse,
using &processTVs=`1` calls the chunk in raw html form.
Thanks for all the suggestions, but the problem keeps coming back to punctuation marks in the posts' H1 headlines causing the content to disappear.
Which makes me suspect there's some sort of coding inconsistency/conflict somewhere.
It doesn't happen in the body content, the h2 headlines or the TV, just the main post title.
The title comes from the chunk template which means this
<title>[[+pagetitle:htmlent]]</title>
is likely where the problem is coming from.
Anybody see any errors there?
Thanks
