[סגור] WPML translation editor

Background of the issue:
I am trying to edit translations on WPML sites. None of it works, apart from automated translations. Link to a page where the issue can be seen: קישור נסתר

Symptoms:
Until a few months ago, I could edit single lines of a translation. This is no longer possible. It is not possible to translate paragraphs with DeepL. It is not possible to edit any line in the WPML translation editor. The only thing I can do is to correct texts directly on the post of any language, which is sub-optimal and takes a lot of time.

Deactivating all other plug-ins does not fix it. As the translation page is on your servers, I guess it has not a lot to do with any of my sites directly?

Questions:
Why can't I edit single lines of a translation anymore?
Why is it not possible to translate paragraphs with DeepL?
Why can't I edit any line in the WPML translation editor?

Any help appreciated!
