A few months ago I asked a similar question: Is it possible to remove the main rich Text box editor? and got the following answer:
function remove_pages_editor(){
remove_post_type_support( 'page', 'editor' );
}
add_action( 'init', 'remove_pages_editor' );
This code removes the editor from all pages. Can I remove if from specific pages (by post-ID) somehow? Thanks!
