Kimopreis Got it, thanks for clarifying. I can see that you're using Jetpack, so when pushing the new content you'll want to clear the cache at Jetpack or if content won't update try disabling the plugin.
Just a side note, the new English version of the domain isn't approved by Ezoic or Ad Manager right now, so won't be eligible to show ads on that version of the site at this time, you'd need to get Ezoic and Ad Manager approval on the new domain to show ads 🙂
