Hello, @DevYb,
I have just checked your site now and the Wishlist OffCanvas content is already translated properly, here is the screenshot: https://postimg.cc/gwHnzk5H
I have checked your site Wishlist page as well, and the content is already translated on it as well except Add to Cart button text, here is the screenshot: https://postimg.cc/Wqhypz9D and to translate the Add to Cart button text, you have to go to Yith >> Wishlist >> Wishlist Page Options and change the Add to Cart text from there: https://postimg.cc/Jtkc8jxN
My Account and Wishlist Text is also and already translated properly on your site: https://postimg.cc/ZCfrFj5h
How and where you added the text below the products on the Category pages? Could you please share the screenshot and also the page URL as well for me to check?
Regards 8Themes Team.
