Got this error on an vbulletin forum with vbseo after enabling "Cache Type" xCache in vbseo admin / General settings

[28-Sep-2014 07:15:58 UTC] PHP Warning: xcache_isset() [<a href='function.xcache-isset'>function.xcache-isset</a>]: XCache var cache was not initialized properly. Check php log for actual reason in /home/myusername/public_html/vbseo/includes/functions_vbseo_cache.php on line 84
the functions_vbseo_cache.php
switch ($this->cache_type)
{
case 1:
if ($this->connect())
$rdata = $this->mchandle->get(VBSEO_CACHE_VAR);
break;
case 2:
$rdata = apc_fetch(VBSEO_CACHE_VAR);
break;
case 3:
if (xcache_isset(VBSEO_CACHE_VAR))
$rdata = xcache_get(VBSEO_CACHE_VAR);
break;
case 4:
$rdata = eaccelerator_get(VBSEO_CACHE_VAR);
break;
}
I want to ask if xcache is properly set on my linux server, if anyone knows what is the issue?
