well i inputted your first suggestion like this below,
$config['encryption_key'] = "xxxxx-xxx-xxxxxxx-xxxxx-xxxxxxxx";

and it worked. why is this?

or is this key below the recommended one?
$config['encryption_key'] = "92428-269-2593438-74736-34630529";

or i can choose any value i like?

thanks in advanced.
