xcache errors

[Mike Edge]

I am trying to set up XF on a server with Litespeed that has a 2x quad core lisc. But I am getting errors loading.

In my config file I had

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
'caching' => true,
'automatic_serialization' => true,
'lifetime' => 3600,
'cache_id_prefix' => 'xenforo'
);

But as soon as I add the backend code, I get errors loading.

$config['cache']['backend'] = 'xcache';

In Litespeed module XCache is enabled?
