Как вариант
while($pl = @$players->fetch_object()) {

while($pl = $players->fetch_object<-()) {


попробую)

окей

Вообще перестает работать) while($pl = $players->fetch_object<-()) {

ошибки нет но пустая страница)

заплачу 100 руб за помощь!

Это попробуй если не поможет пиши мне
object mysqli_result::fetch_object ([ string $class_name = "stdClass" [, array $params ]] )
