Fungsi crud pada codeigniter telat merespon

Ane lagi bikin web dengan codeigniter framework. Ketika mengerjakan di localhost fungsi CRUD berjalan dengan baik, namun ketika ane upload ke hosting muncul masalah pada fungsi CRUD.

Ane harus refresh page berkali-kali atau pergi ke laman lain kemudian balik lagi agar efek dari CRUD berjalan, jadi data yang ane hapus tidak langsung hilang, yang diedit tidak langsung berubah dan yang dibuat tidak langsung ada harus di refresh berkali-kali atau pergi ke laman lain dulu. Kira-kira apa yang mesti dikoreksi yak agan2?

Ini Model-nya

public function create_highlight(){
        $data = array(
            'head' => $this->input->post('head'),
            'text' => $this->input->post('text'),
            'kecamatan' => $this->input->post('kecamatan'),
            'kelurahan' => $this->input->post('kelurahan')
        );
        $this->db->insert('highlights', $data);
    }
public function update_highlight(){
        $data= array(
            'head' => $this->input->post('head'),
            'text' => $this->input->post('text'),
            'kecamatan' => $this->input->post('kecamatan'),
            'kelurahan' => $this->input->post('kelurahan')
        );
        $this->db->where('id', $this->input->post('id'));
        return $this->db->update('highlights', $data);

    }
public function delete_highlight($id){
        $this->db->where('id', $id);
        $this->db->delete('highlights');
        return TRUE;
    }

Ini Controller-nya

 public function creating_highlight(){
        if($this->session->userdata('level') === '2'){
            $data['judul'] = 'Buat Highlight';

            $this->form_validation->set_rules('head', 'Judul', 'required');
            $this->form_validation->set_rules('text', 'Baris I', 'required');
            $this->form_validation->set_rules('kecamatan', 'Baris II', 'required');
            $this->form_validation->set_rules('kelurahan', 'Baris III', 'required');

            if($this->form_validation->run() === FALSE){
                $this->load->view('global/header');
                $this->load->view('global/nav_dashboard');
                $this->load->view('global/side_dashboard');
                $this->load->view('highlights/create_highlight', $data);
                $this->load->view('global/footer');
            }else{
                $this->highlight_model->create_highlight();
                $this->session->set_flashdata('creating_highlight', 'Highlight berhasil dibuat');
                redirect('highlights/index');
            }
        }else{
            redirect('home');
        }
    }
public function updating_highlight(){
        if($this->session->userdata('level') === '2'){
            $this->highlight_model->update_highlight();
            $this->session->set_flashdata('updating_highlight', 'Highlight berhasil diupdate');
            redirect('highlights/index');
        }else{
            redirect('home');
        }
    }
    public function deleting_highlight($id){
        if($this->session->userdata('level') === '2'){
            $this->highlight_model->delete_highlight($id);
            $this->session->set_flashdata('deleting_highlight', 'Highlight berhasil dihapus');
            redirect('highlights/index');
        }else{
            redirect('home');
        }
    }

dan ini View-nya

<div class="container text-center">
                    <div class="intro">
                        <?php foreach($highlights as $highlight ):?>
                        <h1><?= $highlight->head?></h1>
                        <h3><?= $highlight->text?></h3>
                        <h5><?= $highlight->kecamatan?></h5>
                        <p><?= $highlight->kelurahan?></p>
                        <small><?= date("d/m/Y", strtotime($highlight->date))?></small>
                    </div>
                    <div class="card-footer">
                        <?= form_open('highlights/deleting_highlight/'. $highlight->id);?>
                            <a class="btn btn-sm btn-warning" title="Edit" href="<?= base_url('highlights/editing_highlight/'. $highlight->id)?>"><i class="fas fa-edit"></i></a></td>
                            <button class="btn btn-sm btn-danger" type="submit" title="Hapus" onclick="return confirm('Yakin hapus data?')"><i class="far fa-trash-alt"></i></button></td>
                        </form>
                    </div>
                    <?php endforeach;?>
                </div>
