Background of the issue:
I am trying to configure WPML on my developer site after installing WordPress. I encountered an issue with the REST API test endpoint: "The REST API test endpoint скрытая ссылка is not responding correctly." The issue can be seen at скрытая ссылка.
Symptoms:
I expected to see 'REST Enabled yes' under >WPML >Support, but instead, I got 'REST Enabled no'.
Questions:
Why is the REST API test endpoint not responding correctly?
How can I enable REST API support in WPML?
