 * Hello, i’m using a child theme with flat bootstrap. Since the site upgraded to
   4.8 there have been errors on the edit screens. A flash of styled text appears
   as it should then gets removed and the following appears.
 * “Failed to load content css: ‘domain.com’/wp-content/themes/flat-bootstrap-child/
   css/editor-style.css”
 * From what i can gather themes can’t use [@import](https://wordpress.org/support/users/import/)
   on stylesheets any more and Flat Bootstrap seems to use it a lot to include the
   theme styles into the back end.
 * I’m having no luck fixing it so far even by invading the parent theme.
 * Is an update to flat bootstrap due soon?
