Lightbox Content Not Appearing

I've got two clients experiencing similar issues.  When a lightbox appears onscreen, the content never loads (the content is a PDF).  I can't recreate it on my end.  It works as it should on our local LMS and on SCORM Cloud.  

Has anyone experienced this type of issue before?  If so, were you able to rectify it?

BTW, the LMS' being used by the clients are Cornerstone LMS and SuccessFactors.

Thanks in advance for any help you can provide!
