Dear Boris, I made a a page using Tablepress with lot of Flipbooks in it. It all works fine in the admin environment. But as soon i logout it all stops working! I m a newbie and afraid i did something very wrong. Getting a little crazy here.

The page: https://www.archeologiegorinchem.com/testliteratuur/ Im using Nirvana theme. It got a field to add xtra javascript. I guess i make mistake in it:

window.PDFJS_LOCALE = { pdfJsWorker: ’//www.archeologiegorinchem.com/wp-content/plugins/3d-flip-book/assets/js/pdf.worker.js’ }

Please help!. I love your plugin and made over more then 200 flipbooks at my site, but now i like to see them in a table.Kind regards, Martin
