WPML and Business Service Theme compatibility

since I installed the WPML plugin my front page has been missing a lot of elements. There is obviously no way to get rid of this error. Even remove the plugin and clean the wpdp had no effect. Affected is only the front page http://www.roofus.at the other pages work fine http://www.roofus.at/ueber-uns

Thanks for help.

Kind Regards,
