Chrome users may find PDF content loads inside a frame without downloading. If you encounter an error, "failed to load PDF document", when you click on a “standard access” PDF link in Chrome, then you can fix the problem by disabling the built-in PDF plugin as follows:
Type or paste chrome://settings/content into address bar
A pop-up labeled "Content Settings..." will open
Scroll down to the bottom to "PDF Documents"
Select or deselect the check box labelled "Open PDF files in the default PDF viewer application"
Select the option for Download PDFs.
