My Grid Not Displaying but only the footer note is displaying.

Here is my code-"

require_once(APPPATH. 'libraries/phpGrid_Lite/conf.php');
$data['phpgrid'] = new C_DataGrid("SELECT * FROM tbl_division", "fld_uid", "tbl_division"); //$this->ci_phpgrid->example_method(3);
$this->load->view('welcome_message', $data);

"

–"You are using phpGrid Lite. Please consider upgrading phpGrid to the full version to have great features including edit, master detail, and grouping, composite key, file upload, and premium themes!"

I checked the console and found many error for css and js that saying 403 forbidden error. Is there any solution?
