Upgraded to 3... can't access pages

I've upgraded to CodeIgniter 3 and followed the guide, changed all my controllers to Ucfirst. I only have 5 controllers, this isn't a huge site.

My config is as such:

Code:

$config['base_url'] = 'http://www.eldermaltreatment.com/'
$config['index_page'] = '';
$config['uri_protocol']    = 'AUTO';

I can easily access www.eldermaltreatment.com, but cannot access www.eldermaltreatment.com/about.

404 everywhere.

Any suggestions?

EDITED to remove $_SERVER... based off NARF's suggestion.
