Hello, @Roobinda,
Sorry for the inconvenience, but we do not support Classico anymore. We recommend switching to another theme like (XStore) which is the most powerful WordPress Theme.
Yes, we will surely help you in switching the theme, you can start on a fresh new WordPress as well from scratch to avoid inconvenience.
Further, If you want paid Customization services submit a customization request to WPKraken team.
Regards 8Themes Team.
