Codeigniter + GoCart CMS + Dreamhost (Shared Hosti

I have been working on a site locally (WAMP) and it's worked 100%. Now I'm trying to put it online on the client's Dreamhost server and it's been giving me 5 days of problems.

However, on the index.php page, it reads:

An Error Was Encountered Unable to locate the model you have specified: Settings

The structure of the server is:

home
- user
  - domain1.com
    - application/
    - system/
    - index.php
  - domain2.com

.htaccess:

Options +FollowSymLinks

AuthType Basic
AuthName "Restricted Access"
AuthUserFile "/home/user/domain1.com/.htpasswd"
Require valid-user

RewriteEngine On

RewriteCond %{REQUEST_URI}::$1 ^(.*?/)(.*)::\2$
RewriteRule ^(.*)$ - [E=BASE:%1]
RewriteBase /home/user/domain1.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ %{ENV:BASE}/index.php?/$1 [L,QSA]

In config.php, my base_url is:

$config['base_url'] = 'domain1.com';

And the place where the unfound Settings model is being called is located in GoCart's application/controllers/Bootstrap.php file around line 143. It reads

    //autoload some libraries here.
    $this->load->model('Settings');
    $this->load->library(['session', 'auth', 'form_validation']);
    $this->load->helper(['file', 'string', 'html', 'language', 'form', 'formatting']);

Because I am using the GoCart CMS, Settings.php is not in the models folder, but it is in application/modules/settings/models.

That's about the only info I can provide. I'm not sure what's going wrong between the local version and the web version, but I've found a lot of articles and forum posts about Dreamhost causing issues with CodeIgniter. I think it works with CodeIgniter, but now GoCart is causing some issue, and GoCart unfortunately is not as documented as CodeIgniter (so answers are harder to find).

Any ideas?

For future reference: GoCart CMS creates a manifest file (application/config/manifest.php) which overrides other routes and documents the URLs of all the controllers it uses. Apparently, when you install GoCart on a local server, it sets up local paths to the files and these were being used on the web server. I deleted manifest.php and GoCart rewrote a new one. Now it works!
