Hi!
I followed these steps:
Download your .po language file from your server directory using your FTP wp-content/themes/atelier/languages/fr_FR.po.
Search through your strings and amend the translations to your requirements and un-check the fuzzy translations (marked in yellow).
Click File => Save as.
When finished, click File => Compile to MO.
—— Originally there is no fi_FI file on directory, so I downloaded en_US and translated it, saved and compiled to MO fi_FI
Upload both your new language files fr_FR.po and fr_FR.po to the folder wp-content/themes/atelier/languages/.
—— Did this, but nothing happens.
Any ideas whats wrong?
