php mysqli prepared statement: can't echo, print or get anything from var_dump AFTER execute command

I am starting to use mysqli and I got it working on my virtual server but can't get it working on my real server. The databases are the same. I have tried both store and get_result. Any idea what am I doing wrong?

Everything I try to echo, print or var_dump does not show up IF Place after execute but the command will be executed. It worked well on UPDATE and INSERT.

<?php

$mysqli = new mysqli("127.0.0.1", "user", "pass", "db", 3306);
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
  }

echo $mysqli->host_info . "\n";

$sam = 1;


$stmt = $mysqli->prepare("SELECT released FROM svers");
$stmt->execute();
echo "#";
var_dump($sam);
$res = $stmt->get_result();

var_dump($res);

$row = $res->fetch_assoc();
var_dump($row);


$mysqli->close();

The host_info is displayed as "127.0.0.1 via TCP/IP" followed By the # I echoed inside the if() but can't get anything from my database. Even the other # between the $row[ ] info are not showing. Here is my code:

<?php

$mysqli = new mysqli("127.0.0.1", "user", "password", "database", 3306);
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
  }

echo $mysqli->host_info . "\n";

$stmt = $mysqli->prepare("SELECT * FROM svers ORDER BY released DESC LIMIT 1");

if ($result = $stmt->execute()){
    echo "#";
    $result = $stmt->get_result();
    $row = $result->fetch_array(MYSQLI_BOTH);
    echo $row['version'] . "#" . $row['released'] . "#" . $row['note'];
    $stmt->free_result();
}else {
    echo "error";
}
$mysqli->close();
?>
