mysql_fetch_object(): supplied argument is not a valid MySQL result resource in public_html/games.php on line 16

[Phill Hargreaves]

I have this script that has been running fine up to when my host upgraded
there sql to version 4.1.21-standard and php version 4.4.4

I am now getting a few errors and nothing will work now.
Can I get some help please?

The errors I am getting are:
PHP Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /public_html/cats.php on line 5

Here are lines in the cats.php file:
4: $qr1 = mysql_query("SELECT * FROM cats WHERE id=$id");
5: $cat = mysql_fetch_object($qr1);

PHP Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /public_html/games.php on line 16

Here are lines in the cats.php file:
15: $qr1 = mysql_query("SELECT * FROM games WHERE cat=$id AND status=1 ORDER BY id DESC LIMIT 30");
16: while( $row = mysql_fetch_object($qr1) ){

the other file I am get errors in now shows this:
Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /public_html/games.php on line 16

Here is the code that is having the problems:
<?

include("common.php");

if(@$_COOKIE["rating_$itemid"] != ""){
}else{
if($_POST['rateit']){
$sql = "UPDATE games SET vote=vote+1,sum=sum+".$_REQUEST['rateit']." WHERE id='".$_REQUEST['itemid']."'";
mysql_query($sql) or die( mysql_error() );
$itemid = $_REQUEST['itemid'];
setcookie("rating_$itemid", "1", time() + 3600 * 24 * 30);
}
}
Line 14: mysql_query("UPDATE games SET played=played+1 WHERE id=$id");
Line 15: $qamesid=mysql_query("SELECT * FROM games WHERE id=$id");
Line 16: $game=mysql_fetch_object($qamesid);
Line 17: $seo_title = $sitename." - Play ".stripslashes($game->name);

include("header.php");

if( strstr($game->flash,".dcr") ){
?>

I am a newbie to mysql so I have no idea how to fix this, I have alot of people
that play on my game site, so I need a fix soon please?

Thanks Regards, Phill
