I use the gutenberg editor with some custom styling applied in the backend. These css files are added with editor-styles.
So I have added editor-styles theme support:
add_theme_support( 'editor-styles' );
and I load the stylesheet with the add_editor_style() function. I do this in the after_setup_theme.
Everything works fine on my localhost, and also on my (online) test server. I can see the custom styling and it is prefixed with the .editor-styles-wrapper in the body as expected.
But now I moved this website to the live webserver and the editor-styles css files are loaded with a 200 status, but there is no prefixed version of them in the body. I cannot find any other case like this.
The server configuration of the live server and test server are identical.
What could be causing this problem?
