I created in includes/languages/english a folder called custom and coppied the files into it that i wished to change such as header, index, and metatags and none of them would override my main shoppingcart page. I tried again and again and I ended up having to change core files in the english folder because the files in my custom folder were not picked up- is there somewhere i am supposed to tell zen cart to look in the includes/languages/english/custom folder??
