Constant Contact API - php

Question

I'm trying to write a simple Constant Contact script for adding and updating emails. The script is simple enough and should've ran smoothly. But when I start to include 'src/Ctct/autoload.php' the page just returns blank. I tried running it on another server and it works. But on my working server, it returns blank. It uses OAuth authentication from CTCT. I think it's a setting in the server, but I have no control over the server and any changes need to be forwarded to an admin, I just don't know what I need to change.
Here's the code:
require "Scripts/ConstantContact/src/Ctct/autoload.php";
use Ctct\ConstantContact;
use Ctct\Components\Contacts\Contact;
use Ctct\Components\Contacts\ContactList;
use Ctct\Components\Contacts\EmailAddress;
use Ctct\Exceptions\CtctException;
define("APIKEY", "*** Censored Media (18+ only) ***");
define("ACCESS_TOKEN", "*** Censored Media (18+ only) ***");
$cc = new ConstantContact(APIKEY);
// attempt to fetch lists in the account, catching any exceptions and printing the errors to screen
$lists = $cc->getLists(ACCESS_TOKEN);
$action = "Getting Contact By Email Address";
$Email = "asdf#asdf.com";
$FirstName = "Asdf";
$LastName = "Ghjk";
// check to see if a contact with the email addess already exists in the account
$response = $cc->getContactByEmail(ACCESS_TOKEN, $Email);
// create a new contact if one does not exist
if (empty($response->results)) {
$action = "Creating Contact";
$contact = new Contact();
$contact->addEmail($Email);
$contact->addList('1');
$contact->first_name = $FirstName;
$contact->last_name = $LastName;
$returnContact = $cc->addContact(ACCESS_TOKEN, $contact);
// update the existing contact if address already existed
} else {
$action = "Updating Contact";
$contact = $response->results[0];
$contact->addList('1');
$contact->first_name = $FirstName;
$contact->last_name = $LastName;
$returnContact = $cc->updateContact(ACCESS_TOKEN, $contact);
}
// catch any exceptions thrown during the process and print the errors to screen
if (isset($returnContact)) {
echo '<div class="container alert-success"><pre class="success-pre">';
print_r($returnContact);
echo '</pre></div>';
}
print '<p>'.$action.'</p>';
Again, this works on another server I tried, but doesn't work on my working server.
Any help would be appreciated.
Thanks!

Are you running PHP 5.3 or higher on the other server? Also did the domain change at all, if so that may throw an exception resulting in a blank page as your API key is domain specific. Feel free to shoot me an email and I will be glad to help you out with this - mstowe [at] constantcontact.com
