First, thank you for your work, I like this plugin.
As it didn't exist, I was trying to make po/mo files in French, in order to use it here in France. Job done with poEdit.
But when I load these po/mo files in my site, then the page doesn't display the calendar.
Everything else is fine : name, phone, email, captcha are displayed, but not the calendar.
I can send you the po/mo files if you need them to test, but can you help ?
