After I had install the flatly template from bootswatch (https://bootswatch.com/flatly/) the normal modal window of twbs is not working anylonger.
<a data-toggle="modal" href="#" data-target="#myModal">CLICK!</a>
.
.
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</body>
</html>
It is work perfectly until I add the theme into my application.
This means that the modal window appear, but it is not active. the modal window appears behind the grey background. the modal window has not the focus. I can't close it too. But why?
