 * Good morning, I have installed your plugin (version 1.15.2) on a wordpress 6.2.3
   installation with a custom theme. When I try to add a thumbnail image to a 3d
   Flipbook post, the part of the screen where I edit the post goes white and on
   the browser console I get a TypeError from the edit.min.js file, stating that‘
   path is not defined’.

 * Good morning again,
 * we use the plugin on two (2) types of pages, one that has a single flipbook (
   like this [one](https://www.philenews.com/downtown-flipbook/)) and one that has
   multiple (like this [one](https://www.philenews.com/psifiakes-ekdosis-periodikon/)).
   On the front-end everything works exactly as expected, the problem is with the
   administration part of the website, where we get this kind of problem. Up until
   about a couple of weeks ago, everything worked well but and that is the weird
   part, it stopped working with us making any changes to website. At least not 
   that I am aware of .
 * Best Regards,
 * Panagiotis
