no cart.php age being created

Have started a new site and created eCart as per normal. However, on this occasion when I go through the setting up process I get all the pages set up for me excluding the cart.php page - so when i try to add Add to Cart buttons I am unable to do so. Could you tell me what might be the problem? Didn't know what other info to add at the moment to this question but can give you any info required for help

The cart.php page isn't created automatically by any wizards. You need to create that page manually by creating a blank page and using the eCart Display manager to add a cart display to the page. Then you update your add to cart server behaviors to redirect to that page.
