I was see the PayPal extention there's no file extends Model

And why then the controller requests the model?

This is the first time to show this error, I didn't know why to get this error.
And in the Admin folder no need to create a module folder.

I solve it. I was adding unnecessary line after removing is working
$this->load->model();

Thank you
