how am I supposed to use this without a php file???
This is not WP plugin. It is jQuery plugin http://3dflipbook.net/getting-started
If you need WP version use https://codecanyon.net/item/interactive-3d-flipbook-powered-physics-engine-wordpress-plugin/19389832
Ok thank you. Do I need to purchase again or can I use the same product code? Intended to purchase the plug-in.
Purchase another one and open a refund request for this one.
