I am using the google document embeder plugin. I uploaded a PDF to my wordpress media library.
When I copy and paste that link directly into the browser, or try and embed it into my website I get the following error message.
If this message is not eventually replaced by the proper contents of the document, your PDF
viewer may not be able to display this type of document."
I upgraded to the latest version of Adobe to be safe. Please see this image that illustrates the problem clearly.
