Save Button on CKEditor not Work

Hi all,We have an edit page with an HTML editor. When we make changes on the HTML editor and hit the “Save” button inside the HTML editor. It goes back to the list page and show a message “Updated successfully”. But the changes are NOT saved.Is there a way to fix it? And is there a way to hide the “Save” button inside the HTML editor?

You may change CKEditor config by the “create.editor” client side event, the Save button is not applicable, you may hide it by, e.g. in global Startup Script

$(document).on("create.editor", (e, args) => args.settings.removeButtons = 'Save');

Also read CKEDITOR.config.

The “Save” button is hidden after we updated to the latest template. Thanks.
