3D FlipBook - 3D Flipbook bug in Safari

Hi Ivan,

there’s a bug with the 3D Flipbook plugin in Safari (Version 26.3): In the Wordpress backend the thumbnail doesn’t show, “book is processing” stays forever, and all options from “Book properties” are greyed out.

Console error in Safari:

Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating ‘PDFJS.GlobalWorkerOptions’)

Same setup works fine in Chromium, no console errors there.

Could you take a look and see if this can be fixed?

Thanks!
