VPS + Nginx + Xcache not working on Wordpress

Hi all,

I have had a site running successfully on Apache with FastCGI PHP 5.3 and Xcache Enabled with Wordpress. I was using the W3TC (W3 Total Cache) plugin and all was well.

Recently I switched over to Nginx to save on resources and was able to get it working well, however W3TC refuses to let me use Xcache. I have even tried installing Xcache manually.

I am using the Default Nginx with

exec /dh/cgi-system/php53.cgi $*

Xcache is enabled both in the VPS menu of the DH panel, as well as at the Domain level.

I am using the nginx.conf specs provided by W3TC as well as [xcache] edits for php.ini.

The Xcache option continues to be greyed-out in the plugin config.

Can anyone help?
