Hi,
I had the same problem and no translation plugin was able to solve it. I tried loco translate, WPLM, but it didn’t work, so I had to translate the .php file.
Here’s the path:
public_html/wp_contents/plugins/grimlock_buddypress/templates/members/bps-form-home.php
In that file you change the source code:
‘From’ on line 94
‘to’ on line 104
and ‘Submit’ (if you couldnt translate it, but i could) on line 285. I left the ” around the words, I don’t know if the code would work without it, because I tried without, but even though I cleared the cache, the website shouwed the file with the ”, so I just left it like that, I’ll try to change it later.
