My website changes

Hello!

Looks like a nice plugin!
Alltho I got a problem with the plugin. It totally change my layout of the website. I’d much need your help to tell me what causes this. For some reason my full width sections shrinks to boxed style or “in grid”.

(Not sure where to post you an admin login.)
Thank you!
