 * Plugin just displays 403 error. Have tried a bunch of solutions including: blocking
   cache for uploads folders (where pdf is located); checking permissions on folders;
   put CDN in developer mode. All other PDF viewers using js work fine. Just like
   a couple of the features on this one so was going to give it a try. Sorry, can’t
   get it to work.

 * A 403 error is a permissions issue on your server. Unfortunately not much I can
   do there.
