I inherited a highly customized Magento-store. One of the modifications was to hide the
free shipping method from one of the customer groups at checkout. I want to undo this modification, so all customer groups can see free shipping as per the default set up. The problem is, I can't seem to find where the modification has been made. I have checked in the template
app/design/frontend... and in Shipping,
app/code/core/Mage/Shipping . I didn't find any modifications in any files there that would cause this behavior.
Where would a modification to hide a shipping method from a user group on checkout have been made?
