I've translate into french with your guide : http://dev.plogger.org/wiki/CleanUp/TranslatingPlogger
The translation is here : http://rapidshare.com/files/145779201/french.zip.html
But when i put fr.mo file into plog-translations directory and change plog-config.php with fr, all words rest in english, the translation don't apply. What can i do ? I use version trunk-r549.
