We at Easy Website Builder understand that accidents do happen. Hence our Recovery Tool. But the tool only works if you have a saved backup of your site. Without a backup its work-in-progress all over again. That is precisely why we recommend that you continue to save a backup of your site with every Publish or at best with every important update. If you have a back up all you need to do after deletion is to go back to your backup (from the my sites menu), open the stripe that you deleted and press copy. The stripe gets copied on to your clipboard.
