This seems like a fairly straightforward task but I cannot seem to resolve this issue by multiple attempts. Your help is greatly appreciated.

Answer 1

I have no idea about popover plugin, but i have created fiddle for this using bootstrap plugin, when the page gets opened modal will be appear with some content (You can replace it by your content).
Sample HTML:
<div class="container">
<h2>Modal Example</h2>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">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">×</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" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
And JS
$(document).ready(function(){
$("#myModal").modal('show');
});
JSFIDDLE
Note: I did not included popover.js.
