Remote Access cannot be enabled because you do not have a valid API Key or your Elegant Themes subscription has expired. You can find your API Key by <a href="https://www.elegantthemes.com/members-area/api/" target="_blank">logging in</a> to your Elegant Themes account. It should then be added to your <a href="https://www.elegantthemes.com/documentation/divi/update-divi/" target=_blank">Options Panel</a>.
