Bee Offline is plugin that give you a room and freedom to editing and upgrading your WP but not display the error message if 
there is something wrong while editing or upgrading your site, it’s just show “Under Construction” page on screen.
You can change style of your offline page by editing file construction.php inside bee-offline folder.
