hello. i have the same issues with my dreamhost VPS and W3 Total Cache plugin.
I get the error "Warning: xcache_get(): XCache var cache was not initialized properly. Check php log for actual reason in..."
/home/user/domain.com/wp-content/plugins/w3-total-cache/lib/W3/Cache/Xcache.php on line 55
and
/home/user/domain.com/wp-content/plugins/w3-total-cache/lib/W3/Cache/Xcache.php on line 171
I went into that Xcache.php file and checked out lines 55 and 171.
55:
return xcache_set($key . '_' . $this->_blog_id, serialize($var), $expire);
171:
$v = xcache_get($this->_get_key_version_key($group));
I don't know what I should change at this point.
I use Dreamhost and followed these direction:
http://wiki.dreamhost.com/PHP.ini (phprc method)
http://wiki.dreamhost.com/XCache
Any help would be much supported.
Thanks in advance!
