Website ruined after update

Everytime I update my europe-mototours.com website my website is ruined
What is the problem?

Hey There,

Please provide us with additional information. Or example which version you are using and what hosting provider you utilize. As well as the steps you take.

Hosting is siteground
I only update theme x to last version.
Any other details you need?

Can I get some help?

I see that X and Cornerstone are updated in your site and everything looks fine.
