Website broken after update

Hello,

I’m not too sure if i’m at the right place, but I’ll give it a try.
I did an update to the new wordpress where I made my crowdfunding website.
Since then, the website is broken.
Most of the content is gone, and I can’ t login anywhere to administrate it.

The website is https://www.thelabrecords.nl.

Could please someone try to help me with this, because I really have no clue about what to do now…

Thx in advance.

Malik
