The issue I'm having is I want to use Xcache, the php opcode cache for PHP
I've installed it and it works fine, except it only works on ONE domain
I've made sure all domains work in the shard IIS pool, I've also tried copying the PHP.ini file to the domain's httpdocs folder, incase it needs it, but it still won't work

When loading www.thedarkages.info, I get this spammed across my screen

Warning: xcache_isset() [function.xcache-isset]: xcache.var_size is either 0 or too small to enable var data caching in [path]includesclass_datastore.php on line 557

Warning: xcache_isset() [function.xcache-isset]: xcache.var_size is either 0 or too small to enable var data caching in [path]includesclass_datastore.php on line 557

But on this site - www.uoforums.net - There is no error and that forum is using XCache without issue

I've tried increasing the var_size to a higher limit, but it doesn't have any effect.

I was wondering if you might be able to advise?

PHP is running in FastCGI mode right now, I tried setting it to ISAPI mode, but it still threw back the same error
