Gazette theme is not working after move to new hosting on one.com

Hey guys,
in last 2 week I have been creating a website on wordpress using the Gazette theme – https://ucimse.wordpress.com/
after I learnt what I needed, I bought hosting on one.com and using the export/import technology I moved the website to https://www.creativetoday.cz/

But as you can see, it is not the same and few things are not working anymore, especially the “Featured Content” on the top of the site.

Could anyone help please?
