Password post is not translated in theme

Hello!
I have problem with pages with have password, because I can’t translate it anywhere. I’m using Slovenian translate and in the file is translated with this text (This page is password protected. Please enter password to view the page.). The theme is also translated but, there is a bug (I’m using Cordobo Green Park 2 theme). Can I change this text anywhere?

I’ve looked at the post which have change this text with image, but doesn’t work.

Thank you!
