This section in vbseo_sitemap_functions.php:
PHP Code:
if($smart_p_pingbacks)
{
$mp_query = $db->query("
SELECT t_threadid,count(*) as cnt
FROM " . TABLE_PREFIX . "linkback
GROUP BY t_threadid
");
$mp_array = array();
$max_ping = 0;
while ($nextmp = $db->fetch_array($mp_query))
{
$mp_array[$nextmp['t_threadid']] = $nextmp['cnt'];
if($nextmp['cnt']>$max_ping)$max_ping=$nextmp['cnt'];
}
}
Shouldn't it removed? Because linkback table is not a part of vb 3.0.x code and it produces a DB error for me in the cron running. I guess it is accidently forgotten there when importing the hack from 3.6.x code?

When I remove it, hack works fine atm. Just FYI.
