I want to edit WooCommerce's individual product page PHP file. However, I can't find WooCommerce's PHP file. Where on Earth do I find it? It is *not* under Editor with all the other PHP files. Do I use the WordPress dashboard interface, or do I have to go through my Bluehost dashboard?
My website is trialofthecentury.net.
I know a little bit about all this stuff, but I'm still a total amateur---if your explanation is technical, please try and dumb it down for me.
