I'm doing some maintenance on a client's website and for some reason, on a couple of the PDFs featured on this specific page, when I click 'view PDF' I get this showing up instead of the actual PDF: View PDF
The code is below:
</div>
    </div>
    <div class="row border border-second">
    <div class="col-sm-4"><a class="thumbnail" href="#Interest" data- 
    toggle="modal" data-target="#Interest">
    <img class="alignnone wp-image-2067" src="https://st- 
    anns.sheffield.sch.uk/wp-content/uploads/2016/11/Register-of-Pecuniary- 
    Interest.jpg" alt="" width="361" height="324">
    </a></div>
    <div class="col-sm-8">
    <div class="home-content-subtitle">Pecuniary Interest Register <img 
    class="pdf-icon-small img-responsive pull-right" src="/wp- 
    content/themes/bootstrap-canvas-wp/images/logos/pdf-icon-40x40.png" 
    alt="PDF"></div>
    See our Register for Pecuniary Interest here, listing all staff and 
    stating their status within the school.
