I have modify the /system/config.php
define('CACHE_DRIVER', 'file'); to define('CACHE_DRIVER', 'xcache');
But it seems not working...
Xcache is already enable in php.
After I tried to clear the cache in backend admin, the HTTP ERROR 500 was occurred.
The frontstore had no error, but didn't see any effect on frontend.
How can I setup xcache in abantecart and make it working!?
