I converted my old store 2.2.4 to the latest cs-cart. However, in my old store I somehow deleted the USPS 1st class mail (and maybe others). Now, in my new upgraded store, the USPS 1st class mail is still missing since it seems to have moved all the old store settings to the new shop. When I select "realtime" methods...USPS....and go to the dropdown box there is no USPS 1st class mail to pick from (I checked the demo and it's there, just not in mine).
So, how can I restore all the USPS shipping methods so I can have access to choose all options?
