Can't find model -- and it's there

[eluser]WanWizard[/eluser]
and your model files are lower-case? And readable by the webserver (file rights ok)?

[eluser]heliguy[/eluser]
Since your model is called "Registration_model", is your file called "registration_model.php" ?

in my case, User_model is the name of the class model, and user_model.php is the name of the file.

all the files need read and execution permitions, right ?

Try loading your model in lowercase:

Code:

$this->load->model('user_model');

And in the model itself the model name is uppercase?

Code:

class User_model extends Model {
    // code
}
