Background of the issue:
I am setting up a multisite and trying to display translations on the page/post listing page without editing them within the page itself. I have followed recommendations to deactivate plugins on the network admin site. I want the setup and UI to match another site where this plugin is installed.
Symptoms:
I am unable to enable the 'Language' column in the admin UI to show translations on the page/post listing page.
Questions:
How can I enable the 'Language' column in the admin UI for a multisite setup?
Why are the translations not showing on the page/post listing page despite following the same setup process as another site?
Please share the access credentials to the site in your next message, which I have set private. This way, I will be able to double-check the configuration and reproduce the issue.
