MyBB Community Forums

I am having an issue with users trying to register from my main site which has been integrated to MyBB with Integrator. It does not insert into the MyBB database.This worked previously, but stopped working at some point. The only thing I can think of around that time was potentially switching servers. The login still works fine. When someone logs into the main site, they are logged into MyBB. Only Register does not work from the main site. Registration works fine from MyBB as well.

Error message from Registration process in MyBB is "The password you entered is of invalid length. Please enter a password between  and  characters" 
I have a 2 character minimum on passwords in MyBB so that cannot be accurate. I also verified the password is not being lost during the transmission.

Site is https://www.indiefilmshare.com/forum.php

(Register Site):

include_once("integrator.php");
$info = array(
'username' => $_POST['username'],
'password' => $_POST['password1'],
'password2' => $_POST['password2'],
'email' => $_POST['email'],
'email2' => $_POST['email'],
'hideemail' => 1,
'allownotices' => 1,
'emailpmnotify' => 1,
'invisible' => 0,
'receivepms' => 1
);


$register_status = $MyBBI->register($info);

(integrator.php)

define('IN_MYBB', 1);
require_once 'forum/global.php';

require_once 'MyBBIntegrator.php';
$MyBBI = new MyBBIntegrator($mybb, $db, $cache, $plugins, $lang, $config);

Any ideas from the smart people around here?
