Now I can tell, the problem is WPML.
I will address this issue in support of the WPML.
Thank you to everyone who responded and tried to help me.
All the best!

After upgrading WordPress. The site began to work slowly.
If look at the C-Panel:
A very large load on the physical memory. It shows a lot of processes.
One person makes an order …
It may also issue a 508 error.
Plug-ins all have the latest version, I checked.
I disabled some plug-ins. Disables plug-in “Shipping”. The site is still intact slow.
Error.
When a customer wants to pay for the order. It is not possible to select the delivery option.
The block on the page. Where are the buttons for of Delivery – hangs.
You can click the “Checkout”, but there is an error, “You did not choose the delivery.” Here, the process stops.
Prior to upgraded wordpress, everything had worked fine.

But, Rob, for example – have white page. The site does not work on version 3.3.3.
Us need to work! What will you do?
