[Resuelto] automatic sentence translation

Background of the issue:
I am trying to auto translate a sentence using WPML on my website. The issue can be seen on this page: enlace oculto.

Symptoms:
Instead of seeing the auto translation of a sentence, I received an error message: 'Something went wrong, please try again. Error code: Something went wrong. Please contact user support if the issue persists.'

Questions:
Why am I receiving an error message instead of the auto translation?
How can I resolve the error to enable automatic sentence translation?
