I'm quite new in wordpress but as I want to have a trilingual site (EN, FR, IT) I create a multisite network on wp and install also your plugin. Unfortunately, when i go on general settings for each blog, i can't choose anything else but english (or blank).
In the folder lang of my theme (swatch by woo team) I install the .mo files in french.
I also change the wp-config.php writing
define ('WPLANG', 'fr_FR');
nothing happen. I don't have error messages but i still don't have the possibility to change the language.
Could you help me with that please.
