Hello Karen,
I'm sorry if I wasn't clear enough.
That new version of the USPS shipping plugin will display the USPS shipping service name as it is if no translation is added on your translation file, so if you want to change the name of your USPS shipping services you'll have to :
- Go to the page "Hikashop->System->Configuration->Langages"
- Edit your language file
- Add that line if you want to change the name of the "Priority Mail" service :
PRIORITY="My new priority service name"
- Add that line if you want to change the description of the "Priority Mail" service :
PRIORITY_DESCRIPTION="My new priority service description"
