Docs not showing up

I’m using su_document on a few sites. The document shows up as it should here:
http://connect2learningmembers.com/access/assessment-for-learning-planning-for-professional-development/
but not here:
https://www.connect2learning.com/resources/mililani-june29-30-2015-institute/

This is the code for the page that works:
[su_document url=”http://connect2learningmembers.com/access/wp-content/uploads/2015/03/assessmentForLearning2-PRO-DEV-Secured.pdf” class=”pdf”]

This is the code that does not display content:
[su_document url=”https://www.connect2learning.com/resources/wp-content/uploads/2015/04/Hawaii-June2015-Brochure.pdf” class=”pdf”]

Both sites have just been updated to the latest version of SU and all othe shortcodes are working fine.

Thanks
