Ok, it looks like an older version of jquery-ui was causing the trouble. I have updated it and I am finally seeing the thumbnail option again.

I have tried both plugins and getting some results. It works with the default theme, but with my own theme (all plugins disabled) I am still getting the following error:

Uncaught (in promise) TypeError: Cannot read property ‘theme_supports’ of undefined

Will dig some more…

A new WordPress installation did not fix it either…

I just figured out that it might had something to do with javascript, and it looks like it:

I think something went wrong with the update, so I will manually replace some core folders to see if that’s it.

Thanks, I have the first editor.

As you can see, it completely ignores the theme support for thumbnail. So it must be something that conflicts. I already tried disabling/ enabling the ACF Pro plugin, but that wasn’t it. Will try to disable all plugins one by one, see if that helps.

This has nothing to do with the editor as far as I know. Like I said it worked until this update; this is what WP recommends doing and has always worked. I have checked everywhere and can’t find an option to enable/ disable it.
