Hello, I am rather new with .php and I needed to add an ecommerce store to my website. I had to add a dupicate page and todo so I copied the code from the home page and pasted it changed a couple things now when I load that theme my media files dont load anymore. I am trying to do this through wordpress with woocommerce plugin. I am using someone elses non-woocommerce compatible theme and am trying to make this compatible. I havent gotten into the directory parts of .php yet any advice would sure help.
