during my french version of wordpress, i've some untranslated string for example

  • "Published By"
  • "Comments"
  • "leave an answerInch ... "title"

How can i translate such strings please ?

Thanks

Ought to be inside your active theme files, for example comments.php, index.php, page.php, etc. Find out if there's b .p . o . file: Translating WordPress « WordPress Codex
