In the past when I want to place a link to a pdf file on a page I click on Add Media, upload my pdf, select "link to media file" and insert into page. Then there'll be a link to the file. But now when I follow the same process I get a gview shortcode on my page in the editor and the link on the public page just says "Download 8kb". Then when you click on it you download the file. I don't know what has changed. Can I change something to enable the behavior I had previously.
