Only the thread title. If so, edit the vbcms_widget_recentthreads_page template to only have the following code:
HTML Code:
<div class="cms_widget">
<div class="block">
<div class="cms_widget_header">
<h3><img alt="" src="{vb:stylevar imgdir_cms}/widget-forum.png" /> {vb:raw title}</h3>
</div>
<div class="cms_widget_content widget_content">
<vb:each from="threads" key="threadid" value="thread">
<div class="cms_widget_post_bit widget_post_bit">
<div class="cms_widget_post_comment_noavatar widget_post_comment_noavatar">
<h4 class="cms_widget_post_header widget_post_header">
<a href="{vb:link thread, {vb:raw thread}}">{vb:raw thread.title}</a>
</h4>
</div>
</vb:each>
</div>
</div>
</div>
