I am not quite sure if there is actually a new login page set up in the second language. I am using the polylang plugin to deal with the translation, and it seems polylang applies the language of the last page visited on frontend (through a cookie) to the login page. So if my last page visited is in the second language, everything in the login page will show up in the second language but except for the reCAPTCHA. Do you think there is a solution for this?
