Background of the issue:
I'm trying to translate an article on my website hidden link using WPML. I had previously contacted support, but the chat was closed because my IT wasn't available. I want to continue from where the previous conversation left off. The previous conversation can be found here: https://wpml.org/forums/topic/i-cant-translate-an-article-when-i-press-the-translate-button-it-says-that-a-critical-error-has-o/

Symptoms:
I get the message that a critical error has occurred when trying to translate an article.

Questions:
How can I resolve the critical error when translating an article?
Can I continue the support process from the previous conversation?
