Yes, I can. Actually I did it for my site – you can see it here:
https://hisharta.clubpn.org
I’ve found that there are 3 places to be translated:
1. Widget name (default “Users”) – I am using “Сайт посетили” (literally “the site has been visited by”). For “Users” exact translation is “Пользователи”, but it sounds too technical and too official.
2. ” ago” – ” назад”
3. ” Online now!” – ” сейчас в сети!”
For “Last online” the tranlation is “Был в сети”, but it works without changing this one.
Yes, that’s fo ru_RU.
Good luck ?? And thank you for nice plugin ??
