I'm trying to enable both APC and Redis and tried to enable each one separately and cs-cart keeps going blank and can't even access the admin portal after the change. I did change it back to using database and it worked. Please let me know what I could do to enable the APCu and Redis image cache?
Tried to change the following options and my cs-cart goes blank.
$config['cache_backend'] = 'apc';
$config['session_backend'] = 'redis';
