Whilst most storefronts should be using our new "My Orders" page, your storefront may still be using our old one. This can be fixed enabling the setting "New Orders Page" in "Customer Settings".
To do this go to Catfish Administration > Configuration > Settings > Customer Settings and enable the following settings:
“Show unpaid order banner”,
“Show unpaid order link”,
“New Orders Page:”
and set “Hide unpaid order banner for n minutes” to 1.
