Hello,
Thank you very much for choosing our theme and for contacting us.
We do not have the French translation. You will have to translate on your own or search for someone who could share
You can translate all theme and plugin texts via PO file in WordPress. Here is a video tutorial that should help you translate your website texts with a Loco Translate plugin https://www.youtube.com/watch?v=D3NsDdMzsls&list=PLMw6W4rAaOgKKv0oexGHzpWBg1imvrval&index=3
We suggest you keep all the translated files in wp-content/languages/themes/woodmart-pt_PT.po folder. You will not lose your translations after any updates.
Best Regards
