Dear prestashoppers, I was tasked with translating an eshop with 10k+ items where most of them contain name, short description and description. The owner of the website is not a real tech savvy and I do not understand prestashop at all, nor do I have access to the core of it. How do I approach this? The only method I seem to have available is: opening a product, translating the fields in the product overview in their respective language versions, saving the page and rinse&repeat with the next product. Exproting the csv is not an option as this does not include the description field.
