Issue with ImageSelect: Upload - Webcam - Cropper - invalid server response

I purchased ImageSelect: Upload - Webcam - Cropper based on reccomendation and ease of use for my website. I am not a PHP developer nor experienced in the Javascript arena.

When I launch the app, it loads great, finds camera but when I click capture, I get invalid server response. I need a resolution and get this working. I’d be happy to provide the environment data and any other data you need.
