Problem with helper function - works ok locally but not on host

[eluser]gypmaster[/eluser]
Yes, that's right ... my local box is windows and my hosting is linux.

I've changed to

Code:

$config['subclass_prefix'] = 'my_';

in my config file and changed autoloader to load my_security

and called the helper MY_security_helper.php, that throws the same error.

I've left the subclass_prefix as 'my_' and changed the helper file name to my_security_helper.php

that throws the same error.

The change the subclass_prefix to 'MY_' and renamed the helper file to my_security_helper.php

that threw the same error.

So, is there anything else I can do to resolve this?
