Hi @diezmesino,
Please note that our free main plugin is already translated into Spanish, but it is not compatible with multilingual setups. However, the Professional extension adds fully support for WPML and Polylang for WooCommerce (it also adds limited support for TranslatePress, Weglot, and GTranslate)
Thank you Yordan.
According to the documentation you sent me, I can’t find in my PDF Invoices Pro the following settings:
“The Professional extension multilingual settings offer multiple options to define the PDF documents language. You can access this setting from WooCommerce > PDF Invoices > Pro > Multilingual Settings“
Anyway, I have to say that I’m using TranslatePress so if you have any advice or documentation about this, please let me know.
