I’m sorry but I’m not really sure I understand your question correctly. If you mean that there is output content created in the editor at front-end and not text from TinyMCE you can try this get_post_meta($postID, '_mpce_enabled', true); You can get more information at \motopress-content-editor\includes\ce\MPCEContentManager.php file
Thanks John. That is what i need. Some page builders add specific class to body tag, so we can use that selector to make specific style if _mpce_enabled.
