I got this to work on on my site. I am running 3.8.1. Normally I had the problem everyone was getting. It is setup, but it wasn't showing up. So randomly, I checked my newthread style and it wasn't there. So just add:
PHP Code:
<if condition="$show['vbookieevent']">
<fieldset class="fieldset">
<legend>$vbphrase[post_a_vbookieevent]</legend>
<div style="padding:$stylevar[formspacer]px">
<div><label for="cb_postvbookieevent"><input type="checkbox" name="postvbookieevent" value="yes" id="cb_postvbookieevent" tabindex="1" $checked[postvbookieevent] />$vbphrase[yes_post_a_vbookieevent_thread]</label></div>
</div>
</fieldset>
</if>
over:
PHP Code:
$threadmanagement
Works fine now.
