I have a greek core WP installed and its configuration for language in wp-config.php is define('WPLANG', 'el');
When Localization creates language fies it is either el_El.po or el_GR.po and WP doesn't recognize them. When I manually change their name to el.po they work, but then Localization doesn't recognize them anymore to make further editing through its dashboard.
Anyone else having similar problems? How did you deal with it?
