 * Hi,
 * This is most likely due to very old browser that is no longer supported. Please
   share more details:
   1. Your browser version and OS version. (Note internet explorer
   is not supported)2. Link to your page where the flipbook is3. What version did
   you update from? You can also rollback to that version found at: [https://wordpress.org/plugins/3d-flipbook-dflip-lite/advanced/#download-previous-link](https://wordpress.org/plugins/3d-flipbook-dflip-lite/advanced/#download-previous-link)

 * Hi,
 * We found some code conflict with [https://easyreading-cloud.eu/embedded/easy-reading.js](https://easyreading-cloud.eu/embedded/easy-reading.js)
 * If that is crucial we suggest sticking with 2.2.47
 * They are using some self defined function that are now native to modern browsers
   without checking for it’s existence and thus the new variant of PDF.js library
   will not work when it is running on the same page.
 * Best Regards,
   DearHive
