Problem:
The website is in german and needs to be translated in english (sub-folders).

Is there any documentation that you are following?

I was following the wizard from WPML..

What is the link to your site?

https://ocean-re-creation.de/

After clicking on "finish" I have a critical error on the screen.
In the log:

2022/05/12 14:07:28 [error] 3669737#3669737: *6206 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught InvalidArgumentException: element_id and type do not match for element_id:495 the database contains post_attachment while this function was called with post_nav_menu_item in
