Background of the issue:
I am trying to send posts to translation services using the WPML plugin. I was connected with the Blend service, which showed a success status. After selecting a specific page and all translation options, I clicked the 'Translate' button.
Symptoms:
I received a popup with the message 'Sending for translation failed'. The jobs could not be created.
Questions:
Why am I seeing the 'Sending for translation failed' error?
How can I successfully send posts for translation?
