I am trying to:translate my website to other languages: Hungarian, Arabic, Albanian, Russian etc
Link to a page where the issue can be seen:
I expected to see: to be able to translate the page using elementor.
Instead, I got:the message "You must call 'the_content' function...". I tested wpml with the same website but different domain and different server and it works. Maybe this is an issue with WP 5.5?
The issue happens when the languages are hidden and the user doens not have access to view the hidden languages. I can see that from your debug log there are a few language which are marked as hidden.
Please Go to the Users -> All Users page and click Edit next to a user that you want to see hidden languages. On Edit user page find the WPML language settings section, enable Display hidden languages option and click Update User button.
