CodeIgniter Install Issue I Cannot solve

[eluser]bknox360edu[/eluser]
I am getting this error:

Fatal error: Call to undefined method CI_Loader::template() in /var/CI/CI_application/controllers/content.php on line 51

When running a codeigniter install on a linux server with PHP Version 5.3.3-7+squeeze14 debian.

I don't get the error when I am running it on WAMP with Win7 64-Bit PHP Version 5.4.3.

CodeIgniter is version 2.1.3.

That particular function is in the application/MY_Loader.php in the core directory which properly is extending CI_Loader.

Any ideas why this might be happening?
