¿Por qué este código para insertar DB me funciona solo en localhost?

[alvarols]

Este código solo me funciona en localhost. No sé si tenga algún problema para llamar a la API de Twitter.

Si se conecta a la base de datos pero no manda absolutamente nada en el hospedaje que contraté.

Código PHP:

<?php
 
$host = 'localhost';
$database = 'u170904_mapas';
$username = 'u170904_don';
$password = 'Mapa2012a';
 
 
$con = mysql_connect($host,$username,$password);
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db($database, $con);
mysql_query("SET NAMES 'utf8'");
    $data = "http://search.twitter.com/search.json?q=%23ViveBarrio&geocode=20.6946,-103.39755,40km&include_entities=true&rpp=500" ;
    $feed = file_get_contents($data); //Getting the JSON data.
    $valid_data = json_decode($feed); // Converting the JSON data to PHP format.
    $valid_data = $valid_data->results; // Valid data now with just the tweet result.
        foreach ($valid_data as $key=>$status) {
            $screen_name = "ViveBarrio";
        $usuario = mysql_real_escape_string(trim($status->from_user));
        $nick = mysql_real_escape_string(trim($status->from_user_name));
        $profile = mysql_real_escape_string(trim($status->profile_image_url));
        $text = mysql_real_escape_string($status->text);
        date_default_timezone_set('America/Mexico_City'); 
        $time = date("m-d-Y \- g:ia",strtotime($status->created_at));
        $geo1 = mysql_real_escape_string(trim($status->geo->coordinates['0']));
        $geo2 = mysql_real_escape_string(trim($status->geo->coordinates['1']));
        $imagen = $status->entities->media[0]->media_url; 
        if ($media != "thumb") {$media = mysql_real_escape_string($imagen);}
        $id = $status->id;
        $media = mysql_real_escape_string($imagen);
        $caracter = $status->entities->media[0]->expanded_url;
