Answer 1

Make sure the $crud->columns('pk_information_id','information_title','information_status','information_added'); are the field names of your database tables. Try adding $crud->set_primary_key('pk_information_id','"your database table name here"'); if your pk_information_id is set to primary key.

And try to declare $this->_example_output($output, "Manage Brands"); to $this->_example_output($output,'"your controller to view url"'); .
