3D FlipBook - Missing text

All of the text of the PDF is missing. The images and colors and borders show. All text is missing though. This PDF shows fine on a different site (same theme). I thought maybe Imagify was a factor. I deactivated Imagify with no change. All other plugins between the 2 sites are the same. I read a doc from a different flipbook about optimizing the PDF to solve this.

Any thoughts on what is going on?

already heard about similar symptoms - only one idea is encoding/ check server headers for the pdf. What about other PDFs?

It is happening for all PDFs. Can you provide more details about the server headers? Thanks!

Could you provide access to your WP, write me on author@3dflipbook.net, also allow CORS for debugging - insert in .htaccess:

# 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>

we will try to open your PDF from our server.

Thank you very much. Found the issue, it went from /wp-content/themes/cherryframework4/lib/assets/js/cherry-api.min.js. I created canvas using jQuery('<canvas>') for rendering PDF, but after this library it leads to missing text. Fixed the issue.
