Simply does NOT work (Resolved now)

I have the correct shortcode [flipbook pdf=”http://terrybraunstein.com/wp-content/uploads/2017/10/PUMP-2017-Press-Release.pdf”] on this page: http://terrybraunstein.com/pump-2017/ but it’s not displaying the PDF document at all, just showing “Loading viewer …” all the time (trying in Firefox 56).
Even when I place the PDF file outside wp-content folder [flipbook pdf=”http://terrybraunstein.com/tb/PUMP-2017-Press-Release.pdf”] (see the second frame on the same page, then it just displays a general info about the plugin.

4/10 – gave more stars after getting it to work (see the reply below)

Great PDF flipover plugin!

I was pleasantly surprised about the quality of the flipover, when you use a good quality PDF. This plugin gives a much better result with the same file than other online tools like Yumpuu.


  • Very good quality of the flipover, best I’v found so far
  • Good handling: smooth, good zooming
  • Clean and intuitive UI
  • Very easy to embed
  • Good website with clear demos and documentation


  • Width etc. need to be set with parameters in the shortcode, not with CSS or in settings section
  • Missing some options:
    • Can’t hide the “flowpaper” bar at the bottom; maybe a feature for in a paid version?
    • Only two ‘themes’ (light/dark); I would like a ‘transparent’ theme as well

So for a free plugin this is great, but I think there is definitely room for improvement and maybe for a pro version.
