[Закрытые] Jobs could not be loaded - i'm unable to translate any products

Background of the issue:
I'm trying to translate new products on my WordPress site using WPML, but I'm unable to do so. This issue occurs whether I attempt the translation from the product page or directly through WPML. Here is the link to the page where the issue can be seen: скрытая ссылка.

Symptoms:
I expected to see a product list to translate, but instead, I got the message 'Jobs could not be loaded'.

Questions:
Why am I unable to load translation jobs for new products?
How can I resolve the 'Jobs could not be loaded' error?
