I can not display data from the Mysql table on the site

So I was doing a site by local host on wampserver, and it was working normally, now I put it to host hostiger, and it's not pulling any more data from the table. Does anyone know what it could be ??

//Codigo onde mostra os produtos

<?php


               error_reporting (E_ALL & ~ E_NOTICE & ~ E_DEPRECATED);
               require("banco.php");

        $server = "mysql.hostinger.com.br";

$db = "u888901778_users"; // Indique o nome do banco de dados que será aberto

$usuario = "u888901778_jo"; // Indique o nome do usuário que tem acesso

$password = "***********"; // Indique a senha do usuário    



//1º passo - Conecta ao servidor MySQL

$conect = mysql_connect($server,$user,$password ) or die (mysql_error());

//2º passo - Seleciona o Banco de Dados

$select_db = mysql_select_db($db) or die (mysql_error());


          $sql = "SELECT * FROM camiseta_Masc";

          $qr = mysql_query($sql) or die(mysql_error());

          while($ln = mysql_fetch_assoc($qr)){

                    echo '<div class="col-md-4 bottom-cd simpleCart_shelfItem">';
                    echo '<div class="product-at ">';
