Only Russian tried. Yes, one or more words if the numbers enter then everything is fine.

After saving the settings, the plugin works, but the page with the settings in the control panel is not displayed.
Does not work correctly with Russian version of WordPress.
Specifically here, if you write in Russian, and click save then it falls.
