CI goes crazy with iframes

I tried my code on a local Codeigniter 3.1 site, still no problems. It displays just fine.
I even tried calling the iframe as a sub-page with the following code:

Code:

<!-- Main content -->
<section class="content">
    <div class="box box-default">
        <div class="box-header with-border">
            <h3 class="box-title">Test</h3>
        </div><!-- /.box-header -->
        <div class="box-body">
            <div class="row">
                <div class="col-md-12">
                    <div class="text-nowrap dtHorizontalExampleWrapper">
                        <p>Main text goes here</p>
                    </div>
                    <div>
                        <?php $this->load->view('development/admin/iFrame'); ?>
                    </div>
                </div><!-- /.col -->
            </div><!-- /.row -->
        </div><!-- /.box-body -->
    </div><!-- /.box -->
</section>
