Hi,
1. You'll be able to translate every Hikashop translation word by
editing your translation file
through "Hikashop->System->Configuration->Languages".
2.
2.1. You'll find your answer through one of the forum
thread
:
You need to turn off the "show footer" option of the Display tab of the configuration.
2.2. I didn't understood your question.
3. You'll probably have to read the payment method documentation so that when you"ll configure it through "
Hikashop->System->Payment methods->'YourPaymentMethod'".
4. Regarding the payment method that you'll use through your shop, you'll just have to select the best payment method of every payment method used by Hikashop and configure it.
