Fandom Wiki in another language!

Hi, I would like help in a problem with my friend. she and me recently created an account and is having problems with the language of the entire site, the entire site is entirely in Russian and German without her having edited or changed anything! I tried to help but I couldn't and she would like to change the language of the site to English originally, we tried everything and we couldn't, please ask her to help! I'm grateful. :)
