URL is http://www.jonglieren-in-aichtal.de
That's what I get using a web checker:
HTTP/1.1 403 Diese Anfrage wurde von Admin Tools blockiert. Bitte ändern Sie die Meldung in den Einstellungen der Komponente. =>

Translation: This request is blocked by Admin Tools. Please change configuration of the component.
I first deactivated admin tools completely. Result: everthing went fine. No problem with google (no more error with "request like google" in google webmaster tools), but that doesn't solve my problem as I want to use Admin Tools.
Next I compared the whole configuration of the website with another website (also Joomla, same components, admin tools without any problems, same provider). I didn't find any different configuration issues.
Whitelisted domains are ".googlebot.com,.search.msn.com" (default).
Any idea where I can search for more information? The same problem also occures on this URL http://www.tc-bernhausen.de
Thanks.
