Hello,
If you check what file was deleted wp-content/funcs/tpl/plugins/craft/files/snapshots/media.php then you’ll understand that it’s not the file from our theme because it’s not located in our theme directory. We are able to provide support for issues related strictly to our theme. General questions about WordPress security is out of the scope of our support. Post such question on WP support forum.
Be careful when installing third-party plugins from unknown developers.
Regards
