How to identify a code page from WooCommerce based website URL?

I need to correct and enhance an existing WooCommerce based public website - http://ift.tt/1Jf3dA1. I am a newbie to WordPress and WooCommerce.

I need guidance and help please.

I need to locate the page where clicking More Details on the http://ift.tt/1mqjc9H[^] for any product - e.g., under Smoke Detector product.

The way to come to this page is launch http://ift.tt/1Jf3dA3[^] then click Order Now button of blue colored first Free Protection product. Then scroll down a bit and you see a brown colored button with MORE DETAILS test. Clicking this button used to launch a pop up box with more product details.
