Theme Blackbird: change out layout post update

Hi,
I updated the theme blackbird and now the layout has changed completely.
The homepage looked like this originally https://www.flickr.com/photos/124672308@N06/14226923294/ and now it looks like this https://www.flickr.com/photos/124672308@N06/14040501659/

I haven’t edited the code (because I wouldn’t have a clue where to start) and it’s not my theme.

Can someone please help?

The site isn’t live so please view the images to see what I mean.
