PDF FileUpload Snafus

Hi: I used WordPress all the time for a site I maintain and have no problems using the upload media tool to insert a PDF file via a link. However that is with another style, NOT preference lite. With this one (www.pcohc.org) I can’t get the PDF file upload feature to work right like I do with another wordpress style to get a PDF to display after the user clicks the link.

I successfully uploaded a PDF file via media upload. I save the change. But when I click on the link that should kick in the PDF file, I get a black page. Ideas?

Link page where it should work: https://www.pcohc.org/oral-health-resources/ (go to last link)

Thanks.
