Bootstrap 3 (as your question is tagged), requires the modal-content to wrapped in modal-dialog div..

<div id="responsive" class="modal" tabindex="-1" style="display: none;">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
               ...

The progress-bar may be some to other conflicting element on your page.
