I still get errors, does any1 know which functions to modify?

Thnx i a

Michael

OK, found out myself:
In functions.php search for:

// ###################### Start delete thread #######################
function deletethread($threadid,$countposts=1) {
global $DB_site;

// decrement users post counts
if ($threadinfo=getthreadinfo($threadid)) {
$postids="";
$attachmentids="";

$posts=$DB_site->query("SELECT userid,attachmentid,postid FROM post WHERE threadid='$threadid'");
while ($post=$DB_site->fetch_array($posts)) {
if ($countposts) {
if (!isset($userpostcount["$post[userid]"])) {
+++OLD+++ $userpostcount["$post[userid]"] = -1; +++OLD+++
$userpostcount["$post[userid]"]--;
} else {
$userpostcount["$post[userid]"]--;
}

So all you have to do is change $userpostcount["$post[userid]"] = -1; to $userpostcount["$post[userid]"]--;

This was for deleting threads, deleting posts works as shown by tubedogg
Hope I could help some1 with that...
