After they submit a new blank page opens and nothing happens.
Shortcode on this page - [email-download download_id="3" contact_form_id="719"]
Everything seems to work fine, except that the download never loads.
If I right click on the link and choose "Save link as..." it lets me save the correct pdf.
So for whatever reason the custom ID doesnt resolve in the browser but seems to be linking to the correct file.
