Locale Global section in CP bringing back page can not be found
All of your settings look fine.

Most likely what happened is that when you added the new Russian locale under Settings->Locales, the "Resave All Elements" task that needs to run either didn't get a chance to complete or just ran into an error and failed.

If you don't have any Russian content yet, try deleting the locale and re-adding it - making sure that the task in the upper right hand corner completes.  If you already have Russian content, temporarily add any new locale, let the task complete, then delete the temporary locale.  That will also fix it for the Russian locale.
