Any idea why i'm getting this error? memcached installed and running on VB/Joomla/Xenforo at my server fine.

Hello,

Add the following lines to your config.php file:

// CACHE
define('CACHE_BACKEND','mc');
define('MC_HOST','localhost');
define('MC_PORT','11211');

Regards

I'm getting another error in one of my modules as well.
Can you provide step by step what to add/replace for each one of the files so we make sure no version conflict?
Thanks.

Could you send me your config.php without password ?
