Elasticsearch Head plugin is not working for after upgrading ES version from 1.x to 2.x

Thanks for the reply.

I have reinstalled head plugin and also reinstalled whole ES. But it does
not work for me.

I have also used kopf and HQ but head is a very clean ui that's why I
prefer it.

Anyway,
I need to know something that
Does head plugin is supported with newer version ?
And
What about CORS settings it is added either at client ES or Server ES or
Both?

Thanks.
