Steps to reproduce the problem:
- Get access to demo admin at demo.fancyproductdesigner.com
- If you are on Safari then everything will work without problems. If you use Chrome or Firefox then the circle loading icon will spin around indefinitely and the FPD editor will be frozen until you refresh the page.
I know react.js and If you are willing to share the code of the Product Builder with me, then I'm willing to fix this issue for free. It will benefit everyone.
I already explained in the private ticket, that this is not possible. We are using the built-in wp media library to access users images and here you can select only images to use in the product. Fabricjs does not support pdfs. Maybe there is a plugin for wp media library that converts a pdf into images.
