Hope this helps DbOperations.php , should be like this
public function getGender($id)
    {
        $stmt = $this->con->prepare("select gender, dob_year from table_user where id = ?");
        $stmt->bind_param("s",$id);
        $stmt->execute();

        return $stmt->get_result()->fetch_assoc();
    }

mysqli_stmt::bind_param Number of variables doesn't match number of parameters in prepared statement

Hope that helps This is clear example showing why mysqli is totally unusable with prepared statements.
Either use PDO or manually parsed custom placeholders, like safemysql does.

Hope this helps Your query preparation contains zero parameters, since you just dumped the values in there, completely defeating the purpose of prepared statements. Instead, try this:
 if (!($stmt = $mysqli->prepare("INSERT INTO table(id, name, votes) VALUES (?,?,?)"))) {

hop of those help? Modification is:
$stmt->bind_param ( "ss", $user, $pass); because 1 data type is not defind in bind_param (). bind_param() will take two arguments 1st one is types (i, d, s, b) corresponding datatype in your query(?) and 2nd arg are values.
public function login($_username, $_password) {
$this->sessionOpen ();

 if (empty($_username)) {
    $this->log->error ( "Username vuoto" );
    throw new AuthLoginFailed ();
}
if (empty($_password)) {
    $this->log->error ( "Password vuota" );
    throw new AuthLoginFailed ();
}

$db = new mysqli ( $this->sql ['server'], $this->sql ['username'], $this->sql ['password'], $this->sql ['database'] );
if (mysqli_connect_errno ()) {
    $this->log->error ( "Errore di connessione a mysql: " . mysqli_error ( $db ) );
    throw new MysqliConnectionError ( "Mysqli error: " . mysqli_error ( $db ) );
}

$stmt = $db->prepare ( "SELECT id,org_id,org_group_id,people_id FROM users WHERE 'username' = ? AND 'password' = ?" );
if (! $stmt) {
    $this->log->error ( "Mysqli prepare error: " . mysqli_error ( $db ) );
    throw new MysqliPrepareException ( "Mysqli error: " . mysqli_error ( $db ) );
}
echo md5 ( $_username ) . "---" . md5 ( $_password );
//on page username and password is showed at this point
$user=md5 ( $_username );
$pass=md5 ( $_password );
$stmt->bind_param ( "ss",  $user,$pass);
/* Execute it */
$stmt->execute ();
if (! $stmt) {
    $this->log->error ( "Mysqli prepare error: " . mysqli_error ( $db ) );
    throw new MysqliExecuteException ( "Mysqli error: " . mysqli_error ( $db ) );
}


$stmt->fetch($rst);

echo "results: " . $rst->num_rows; //output of this: results:

if ($rst->num_rows == 0) {
    throw new AuthLoginFailed ();
}



/* Close statement */
$stmt->close ();

/* Close connection */
$db->close ();
}

Mysqli:mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement

Hope this helps It is failing because mysqli is not PDO and you cannot bind in a loop. Thus you have to use tricks to bind an array in mysqli. Luckily, if your PHP version is 5.6 or 7, you can use this code:
$stmt = $db->prepare($query);
$types = str_repeat('s', count($param));
$statement->bind_param($types, ...$param);
$statement->execute();

I wish this helpful for you That's not how bind_param works in mysqli. Maybe you were thinking of PDO? In mysqli you have to bind them all at once with one statement.
$stmtPruefung->bind_param("sss",$username, $key, $hwid);
