Bootstrap Modal Popup Not Clickable

Using Bootstrap to add a modal popup. Upon clicking the trigger button, the modal is dark and unclickable. Any idea what's causing this or where to look?

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>


<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</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>

Sometimes, changing the z-index can mess up things with Bootstrap so as they say in Bootstrap documentation, try to place your <!-- Modal --> block on top of your page. If it's a modal that is accessible from many places in your app you can place it in a partial and call it on top of your app/views/layouts/application.html.erb like so (sorry, it's a slim template, tell me if you need erb translation):

doctype html
html
  head
    == render 'layouts/meta'

    = stylesheet_link_tag …
    = javascript_include_tag …
    = csrf_meta_tags

  body

    == render 'path/to/your/modal'

    .container
      == yield

    == render 'layouts/footer'

Otherwise, you could try to do a special <%== yield :modal %> in your application.html.erb and call it from somewhere else with `<%- content_for :modal %>. Not sure about the erb syntax here. It's explained here : Using The Content For Method
