Problems with modal / boostrap

Navigation
3

Hello, I have a problem with my site, I would like it when I click the modal button, it closes and opens the modal again (the following code is a summary code of what I need), in this code, when I I open the page the modal opens automatically, and when I click the close button, it closes and opens, however, when I do this twice, the modal simply does not open anymore and the screen is all black and locked. 

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

</head>
<body>

<div class="container">
  <h2>Activate Modal with JavaScript</h2>
  <!-- Trigger the modal with a button -->
  <button type="button" class="btn btn-info btn-lg" id="myBtn">Open Modal</button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">
    
      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Modal Header</h4>
        </div>
        <div class="modal-body">
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" onclick="functiona()" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>
      
    </div>
  </div>
  
</div>
<?php
      $IdUsuario = $_GET['IdUsuario'];
      $senhaConfere = "nao"

      if (isset($senhaConfere)) {
        if ($senhaConfere=="nao") { 
          echo $senhaConfere;
          ?>
          <script>
            $(document).ready(function(){
              $('#myModal').modal('show');
            });
          </script>
    <?php
        }
      }                
    ?>
}
?>
<script>
function functiona(){
	$(document).ready(function(){
    	$('#myModal').modal('hide');
    	$('#myModal').modal('show');
	});
}
</script>

</body>
</html>

Has anyone ever had this problem, or do you know how to solve it? Thank you in advance!

Friend, you can not put everything in the same function, why you are using it to hide and display them separately, try doing the following: 

   <script>
        function ocultar(){
                $('#myModal').modal('hide');
        }
        $(document).ready(function(){
                $('#myModal').modal('show');
     });
        </script>

Error in table change in PostgreSQL. How do I change the type of a colulna int to the timestamp type? How can I manipulate CSS of the parent element to the clicked element?
