Content Bug

Hi,

I've setted the membershio plugin and set up to strager with a negative rules that except him from seing two categories.

When I activate the plugin something strange is happening :

-> Any posts are displayed execpt the content of the article himself ( we can see title, tages, addthis etc.. but no content. It looks like he's ignoring the
"<div id="content"<?php if ($template == 'full') { echo " class=\"full-width\""; } ?>>"

part in any single.php files.

Any ideas ?
