Help – errors after updating to latest version wordpress

Question:

When logging on to my backend today, I saw the orange-flashing notification regarding update 4.9.1 was ready.

I didn’t think so much about it, and pressed “update”.

Immediately after that I received numerous errors on my page.

I am not able to choose language/country in Woocommerce, and it is no longer possible to buy any products in my shop. The button to go to payment is no longer there.

Can anyone help me out?

Beneath are some of the errors
