Problem with PDF viewer

Software Support
1

Good morning,

I have a problem with the PDF preview in OJS 3.0.1. After adding a galley, on the article page after clicking on the PDF I see only the blue bar at the top of the page and a white background. During the OJS tests everything worked fine, what is the problem?

Please help, in a few days I have to publish a magazine.

hi @lewiatan1989,

Can you download the pdf file?
What error do you get in your php error log?

Hey,
Yes, I can download the file, I do not have only pdf preview.
Recently turned on https, most likely it is a problem, because when you turn off the https everything works properly.
I was trying to change the “X-frame-Options” setting from DENY to eg SAMEORGIN but that did not work.
Does this plugin not work with https?
