Array To String error / undefined $query

In your controller, you are calling the render method like this:

PHP Code:

$this->render('admin/docs/existing_view', $data); 


Where the second parameter $data is an array of objects.

However, in your MY_Controller, the render function expects a string as the second parameter:

PHP Code:

protected function render($the_view = NULL, $template = 'master') 


That's why you are getting the array to string conversion error.

Thank you for your answer! What should I do then?
