Loading a Model - Base_URL???

[eluser]Unknown[/eluser]
Hi, this is killing me. Im a noob and I can't get this right.

I have a website. I load a module in the controller. It works great when the URL is like so:

www.website.com/

But if the website is like so:

www.website.com/projects/project_name/

The whole thing bugs out with the following notice:

Undefined property: CI_Loader::$twitmodel

I am including the model with the following code on all pages:

Code:

$this->twitmodel->twitterfeed();

Let me know if you need more info.
