Modal tidak mau muncul di php

selamat malam, mohon bantuannya saya tidak dapat menampilkan modul untuk "execute" padahal awalnya tidak ada masalah namun sekarang jadi tidak ada respon apa-apa saat menekan tombol "execute", mohon bantuannya, terimakasih.

<button onclick="getfocus()" type="button" class="dropdown-item" data-toggle="modal" data-target="#<?php echo $no; ?>">
                         execute
                      </button>
                    </div>
                   </div>
                      <!-- Modal -->
                    <form class="" action="konf.php" method="post">
                      <input type="hidden" name="id_tugas" <?php echo 'value="'.$row['id_tugas'].'"'; ?>>
                      <div class="modal fade" id="<?php echo $no; ?>" tabindex="-1" role="dialog" aria-labelledby="<?php echo $no ?>" aria-hidden="true">
                        <div class="modal-dialog modal-dialog-centered" role="document">
                          <div class="modal-content">
                            <div class="modal-header">
                              <h5 class="modal-title" id="exampleModalLabel">Password - <?php echo $row['nama_test']; ?></h5>
                              <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                                <span aria-hidden="true">×</span>
                              </button>
                            </div>
                            <div class="modal-body">
                             <input class="" id="myAnchor" style="width:100% !important;" type="password" name="password" placeholder="password">
                              <input type="submit" class="btn btn-primary mt-2 float-right" name="button" value="submit">
                            </div>
                          </div>
                        </div>
                      </div>
