„Cache Zone Path“ does not exist.

Hello ,
I`m trying to setup your plugin , but I get those error message.
I`m using fastcgi_cache.
Nginx is caching fine.
Nginx and php-fpm using the same user (www-data).
And those user have full read/write permissions to fastcgi_cache_path directory.
Does not know what to do with “The Filesystem API needs to be setup so it won’t ask for credentials.”
What I`m missing ?

Thank you.
