I have a heavily modified instance of Magento 1.9 and it does not show Subtotal in the Checkout.
I have found out that in file
renderTotals() always returns empty string, while it should return html. For comparison, in clear installation of Magento 1.9 it does return html strings.
How to find out the cause of this? Is something broken? Is there a setting in the admin section that disables this output?
