My Helper function not found

[eluser]IvanBlue[/eluser]
Hello, I created a helper function and I put it inside application/helpers with the name my_helper.php. In development it works perfectly, I can use the function defined in there anywhere but in production the function are not found. What am I doing wrong?

Thanks.

Hello. Before using the helper you must load it using:

Code:

$this->load->helper('my_helper');
