You may update your Debutify theme to benefit from the new features added. As we keep improving, we will not support some of the older themes and it makes for Shopify store owners to delete themes they no longer use.
How to Delete a Theme From Shopify Admin?
In Shopify admin, under Online store, click on Themes.
Scroll to Theme Library, select the theme to delete, and click on the ellipsis (Actions).
From the list of actions, click on Remove.
Click Remove to delete the theme. The deleted theme will no longer appear in the Theme Library.
