I read this KB article about localization though, the examples are for sub-folders.
I'm wondering how to handle the same concept but, for different language based domains e.g.
I have just one locale (German, de). Now, I've changed my CP language to English ('defaultCpLanguage' => 'en' in general.php).
But now, all my entries have disappeared in the CP (Craft Pro 2.4.2670).
