French translation

Hi, I see this message on WordPress translation:

This plugin is not properly prepared for localization (View detailed logs on Slack). If you would like to translate this plugin, please contact the author.

Can you fix it?
I translate the plug-in in French (lot of terms are not translatable in class-wpdb-admin.php and admin_header_notification.php), you can download my po/mo files here:
