error after installation

Hi,

I have a new fresh install of WordPress and Enfold + dummy data. No plugins.

I have the following error displayed on the top of the page. Also, the “Home” menu link simply redirecrt to http://kriesi.at/themes/enfold/

I have the same issue after multiple re-install. Even without dummy data. Also, despite I do not install dummy data I have all the menu links and “Home” link redirect to http://kriesi.at/themes/enfold/
