After upgrading to 1.2.17 (without errors) entering a domain like "domain1.de" i get redirected to the admin panel... only using www.domain1.de brings up the right page.
Before the update i could just domain1.de without www.
edit: found that the error only happens when using https:// without ssl it works fine, like before.
edit: under /etc/apache2/sites-available no domain1-ssl.conf is generated.
