codeigniter Unable to load the requested file error

[sandstorm140]

Hello!

I have the following code in my controller:

$this->parser->parse('themes/default/index.php', $data);

And getting error:

 

Unable to load the requested file: themes/default/index.php

However, when I type in the same url into the address bar, the page loads fine.

I can't for the life of me figure out what's going on.

Thanks in advance!

ADDITIONAL INFO:

Configs & Helpers are set as:

//Commented lines I've tried.
//$config['base_url'] = '';
//$config['base_url'] = 'http://localhost';
//$config['base_url'] = 'http://localhost/';
//$config['base_url'] = 'http://localhost/PB_MVC';
$config['base_url'] = 'http://localhost/PB_MVC/';
$autoload['helper'] = array('url');

My folder structure is:
-PB_MVC
--application
--system
--themes
---default
