Have any idea what it might be or what I can do to fix it? :)

hmm, please help: I have this code, the micostats work, but the bbuserinfo doesnt:

// ###################### Start dovars #######################
function dovars($newtext,$sendheader=1) {
// parses replacement vars

global $DB_site,$replacementsetid,$gzipoutput,$gziplevel, $newpmmsg,$fullpm,$bbuserinfo, $microstats;
static $vars;

if (connection_status()) {
exit;
}

if (!isset($vars)) {
$vars=$DB_site->query("SELECT findword,replaceword FROM replacement WHERE replacementsetid IN(-1,'$replacementsetid') ORDER BY replacementsetid DESC,replacementid DESC");
} else {
$DB_site->data_seek(0,$vars);
}

$findwords=array(0 => '{getmicrostats}', 1 => '{bbusername}');
$replacewords=array(0 => $microstats, 1 => "$bbuserinfo[username]<!-- auto name hack -->");
$i=1;
while ($var=$DB_site->fetch_array($vars) and $i++) {
if ($var['findword']!='') {
$findwords[$i]=$var['findword'];
$replacewords[$i]=$var['replaceword'];
}
}
$newtext=str_replace($findwords,$replacewords,$new text);
