Background of the issue:
I'm trying to make an automatic translation using WPML, but it doesn't work. The issue can be seen on this page: קישור נסתר. I expected to see the result as shown here: קישור נסתר.

Symptoms:
The default language, English, must be mapped to a supported language in order to use automatic translation. Instead of the expected result, I got this: קישור נסתר.

Questions:
Why doesn't the automatic translation work?
How can I map English to a supported language for automatic translation?
