Child theme is a mess

Hi, there.

After activating the child theme the visualization of the whole page is a mess: http://dvl.webaliza.net/

I tried to add the @import in style.css, but it does nothing.

How can I activate and get running the child theme properly?

Thanks in advance.

Hi,
Creativity theme frontpage is based on widgets, did you configure your widgets properly in your child theme?

I didn't think about that. I will try and let you know.

So many thanks. Best regards.
