i am having a similar problem, but am getting the error message from the controller that the property Site::$site_model is undefined. i have the database library autoloaded, and even have the model loaded in the controller, and still get the same error message. i have done this in two different installations with 2 different versions. i can access the database and pull records. from the controller. i am brand new to codeigniter, but so far am not impressed as i can't get it to work properly. any other ideas?
