Firstly, if you including vB's global.php then there is no need to use mysql_query, use the builtin MySQL functions that coem with vB

PHP Code:

$threads = $DB_site->query("SELECT * FROM thread"); 
while($thread =$DB_site->fetch_array($threads)) { 

    $lastpost = vbdate($dateformat, $thread['lastpost']); 

    echo "$lastpost<br />"; 

} 


If this code is in a function then make sure you have:

PHP Code:

global $DB_site, $timeformat, $dateformat; 


Also note that if the page is outputing templates then the echo isn't likly to output anything to the browser.
