Using 1-Click Upgrade I updated from "1.6.1.16" → "1.6.1.24" → "1.7.8.10". On PrestaShop I had the backend in Polish language. After the upgrade I have in English language.
How can I restore the Polish language of the backend of the store?
I tried to change the Polish language to English before the update, but I have errors during the update:

I am looking for a way to have Polish language for the backend. Maybe it is possible to forcibly overwrite the translation?
