3D FlipBook - Adding flipbook to post or page isn't working

I follow steps you prescribe "Inserting 3D Flipbook into a post". But result is nothing. I don't see flipbook.

Please, help ASAP. Nothing works. Not able to insert flipbook on page or post. Help!!!

I am Having the same problem - I have added the short code and I am just getting a spinning wheel????

I don't get even a spinning wheel!! Empty page or post. No flipbook

Support is a bit disappointing !!!!

Could you write a link to the page where you use the plugin?

CORS issue, add in .htaccess file in the root of kudosshowers.scdn8.secure.raxcdn.com (server where you store PDFs)

# CORS for PDFs
<IfModule mod_headers.c>
<Files ~ ".*\.pdf$">
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Methods "GET"
Header add Access-Control-Allow-Headers: "Range"
Header add Access-Control-Expose-Headers: "Accept-Ranges, Content-Encoding, Content-Length, Content-Range"
</Files>
</IfModule>

I have had the below from the hosting company!

kudosshowers.scdn8.secure.raxcdn.com isn't an Apache server so .htaccess files aren't supported. It's a CDN url which uses the same web server that the website is on as the origin, and it's already configured to pass origin headers rather than domain headers so CORS shouldn't be an issue.

I.e. the files are actually already in the usual wp-content location within the website. Just the front end requests them via the above url so that requests can be handled by localised caching servers instead of the one web server being hammered horrifically.

What else can I do ??

The CORS issue still exists, see https://ibb.co/BcN7Vh2
