Unable to load helpers

[eluser]koryrok[/eluser]
Hi All,

I'm moving my CI application from a windows machine over to LAMP and everything seems to be working fine except for a few custom helpers I created. I get the following error:

Unable to load the requested file: helpers/myfunctions_helper.php

I've verified all custom helpers are FTPd over to the new LAMP environment and I've also tried copying the helpers from system/application/helpers into the core helpers directory and no luck... anyone know why I could be getting this error?

Thanks,
Kory
