Looks like the newthread template has changed in vBulletin 3.8.7..... so, in the AdminCP edit the vBulletin 2 Twitter: Add Hashtag Field To New Thread plugin via Plugins & Products -> Plugin Manager and completely replace the contents with the following:

PHP Code:

if ($vbulletin->options['ms_vbtwitter_enable'] && ($vbulletin->options['ms_vbtwitter_enable_hashtag'] == 1 || $vbulletin->options['ms_vbtwitter_enable_hashtag'] == 3) && (!empty($vbulletin->options['ms_vbtwitter_twitter_consumer_key'])) && (!empty($vbulletin->options['ms_vbtwitter_twitter_consumer_secret'])) && (!empty($vbulletin->options['ms_vbtwitter_twitter_oauth_token'])) && (!empty($vbulletin->options['ms_vbtwitter_twitter_oauth_token_secret'])))
{
    $twitterEnabled = false;
    switch ($vbulletin->options['ms_vbtwitter_forums'])
    {
        case 1: // include selected forums
            $forums = explode(",", $vbulletin->options['ms_vbtwitter_enabled_forums']);
            $twitterEnabled = (in_array($foruminfo['forumid'], $forums)) ? true : false;
            unset($forums);
            break;
        case 2: // exclude selected forums
            $forums = explode(",", $vbulletin->options['ms_vbtwitter_enabled_forums']);
            $twitterEnabled = (!in_array($foruminfo['forumid'], $forums)) ? true : false;
            unset($forums);
            break;
        default: // include all forums
            $twitterEnabled = true;
    }

    if ($twitterEnabled)
    {
        if ($vbulletin->options['templateversion'] >= "4.0.0")
        {
            $hashtag_field = '<div class="blockrow"><label for="hashtags" class="full">' . $vbphrase['hashtags'] . ':</label>
                <input type="text" class="primary full textbox" name="hashtags" id="hashtags" value="' . $hashtag_values . '" maxlength="' . $vbulletin->options['titlemaxchars'] . '" tabindex="1" /></div>';
            vB_Template::preRegister('newthread',array('hashtag_field' => $hashtag_field));
            $vbulletin->templatecache['newthread'] = str_replace('$messagearea', '$hashtag_field . $messagearea', $vbulletin->templatecache['newthread']);
        }
        else
        {
            $hashtag_field = '<div class="smallfont">' . $vbphrase['hashtags'] . ':</div>
                <div><input type="text" class="bginput" name="hashtags" id="hashtags" value="' . $hashtag_values . '" size="40" maxlength="' . $vbulletin->options['titlemaxchars'] . '" tabindex="1" /></div>';
            $search = '<!-- / subject field -->';
            $vbulletin->templatecache['newthread'] = str_replace($search, '$hashtag_field . $search', $vbulletin->templatecache['newthread']);
        }
    }
    unset($twitterEnabled);
}
