we created own theme by extending rwd theme and cart page was using below file code :
app/design/frontend/rwd/theme1/template/checkout/cart/default.phtml
we created custom module and it includes some features in Listing, view & cart page :
after installing module, cart page is displaying using below code.
app/design/frontend/base/default/template/module/cart/item/default.phtml
= > cart page.
we dont need features present in cart page, so we renamed the default.phtml file
but than i thought it will use fallback and cart page will display using below path
app/design/frontend/rwd/theme1/template/checkout/cart/default.phtml
but now in cart page, "name, sku, price" and no other information are displaying.
