Currently your plugin code doesnt check the $useridpost nor use the right logic operator resulting in not letting anyone post if their Global post count is below the option; regardless if they have posted in the specified thread or not.

Here, replace your plugin code in the XML file with this.

PHP Code:

$useridpost = $db->query_first("SELECT userid from " . TABLE_PREFIX . "post where threadid = '" . $threadinfo['threadid'] . "' AND userid=" . $vbulletin->userinfo['userid']);
if($vbulletin->userinfo['posts'] < $vbulletin->options['oldpt_po'] && $vbulletin->userinfo['userid'] == $useridpost['userid'] && can_moderate($forumid, 'canremoveposts') == false)
{
    standard_error(fetch_error('oldpt_error', $vbulletin->options['oldpt_po']));
}
