It may be due to this:
Deprecated: Function split() is deprecated in /opt/local/apache2/htdocs/wordpress-networking/content/plugins/wp-native-dashboard/wp-native-dashboard.php on line 547
Thats what I see right above the select box “Available for download:” on the settings page 🙁
Thirded, broken in 4.2.2 as well.
I switched to the plugin called “Backend Localization” and was back in business. Works fine in wordpress 4.2.2 and I can see the backend in arabic or english. Also works on wordpress multisite 3.9.2

Same, hope fix will come soon!
Unusable since 4.2.2.
The backend language selector messes with the site language selector in WordPress settings.
I hope this will be fixed. I was using this plugin for all my sites.
hm, long time no reply, hope the author is still active.
