Hello,

Make sure you have cleaned the cache. Also, you need to switch the site into the language of translation.
Here is a video tutorial that should help you translate your website texts with a Loco Translate plugin https://www.youtube.com/watch?v=D3NsDdMzsls&list=PLMw6W4rAaOgKKv0oexGHzpWBg1imvrval&index=3

If you still have the problem, provide the stings and site admin access to the private area.

Best Regards
